In a fluid apparatus used as a compressor, a swing support member is constructed of a hook-type adjustable joint, and supports a swing member in capable of swinging while restricting the swing member from rotating about a center axis of a shaft of the compressor. A variable mechanism portion is constructed of a rotary member rotatable around the shaft, the swing member and the like. A slant center around which the swing member swings is made to substantially correspond to a center of gravity of the variable mechanism portion. Therefore, a slant moment, for changing a slant angle of the swing member, is not structurally generated. Accordingly, even when the compressor operates, large vibration and large noise can be prevented, thereby improving durability of the compressor.

Balanced variable displacement fluid apparatus

According to the invention, a compressor having a threaded screw connection portion formed directly on a fitting portion of the housing is provided. Since no through bolt or the like for connecting two-parts of the housing is used, the diameter of the housing can be reduced. However, in a case that a suction port and discharge port do not align with an external mounting structure, a mounting means able to slide on the housing and adjust the positions of mounting brackets at least in the direction of rotation is added.

Compressor with compact screw connected housing and adjustable mounting means

A piston type compressor having a drive plate (swash plate), wherein sliding friction between the drive plate and shoes is reduced and the compressor is made smaller by slidably attaching the shoes engaged with spherical ends of pistons to a shoe holding plate formed with guide grooves in the radial direction and supporting the shoe holding plate by the drive plate through a thrust bearing. The drive plate is connected to an arm of the shaft side through a double slide link mechanism to enable it to be supported by only a front end of the front housing.

Compressor with single shaft support

A damping force detecting apparatus for detecting a damping force of a variable damping force type shock absorber including a cylinder and a piston slidably inserted thereinto. The damping force detecting apparatus comprises a piezoelectric element assembly for generating a charge corresponding to a pressure applied thereto and a pressurizing device for pressurizing the piezoelectric element assembly. The piezoelectric element assembly has a diameter smaller than a cylindrical piston rod fixedly secured to the piston and is housed therein. The pressurizing device is screwed into the piston rod so as to be in contact relation to the piezoelectric element assembly for pressurizing the piezoelectric element assembly in correspondance with a distortion of the piston rod generated in the sliding directions of the piston with respect to the cylinder due to expanding and contracting action of the shock absorber.

Detection of damping force for shock absorber control

An exhaust gas cleaning device for collecting and burning off particulates within exhaust gases discharged from an internal combustion engine of an automobile or the like is disclosed. The device comprises a filter member which is disposed in an exhaust gas passage of the engine for collecting particulates within exhaust gases, an electrically heating member which is disposed on or near the upstream end of the filter member for igniting and burning off the collected particulates, a by-pass passage having a flowing resistance smaller than that of the filter member, which is communicated with the upstream side and the downstream side of the filter member for flowing most of the exhaust gases without passing the filter member at the filter member regenerating time, a valve means which is disposed in the by-pass passage for controlling the exhaust gas amount flowing into the by-pass passage and the filter member by opening or closing the by-pass passage and a valve control means which controls the valve opening so as to flow a small amount of exhaust gases enough to supply the most proper amount of oxygen to the filter member for burning off the collected particulates, into the filter member when said filter member is regenerated.

Exhaust gas cleaning device for internal combustion engine

An exhaust gas cleaning device comprises at least one exhaust gas flowing passage, at least one particulates collecting member composed of two filter elements having different heat capacity, which is disposed within the exhaust gas flowing passage and heating means which is interposed between the filter elements so as to be closely contacted therewith. The filter element having smaller heat capacity is disposed on the upper stream side of the heating means and the filter element having larger heat capacity is disposed on the downstream side thereof. The filter element having smaller heat capacity is rapidly heated by the heating means and the heat of the filter element having smaller heat capacity is transmitted to the filter element having larger heat capacity. All of the particulates collected by the particulates collecting member can be burnt off with excellent heat efficiency.

An exhaust gas cleaning device for collecting carbon particulates in the exhaust gases, is disclosed. The device is provided with a filter member formed of a material having interconnected pores and an electric heater which is buried within the exhaust gas inlet end portion of the filter member. According to the exhaust gas cleaning device of the present invention, the carbon particulates collected in the inlet end portion of the filter member is directly heated by means of the electric heater which is provided in the inlet end portion of the filter member. Therefore, carbon particulates can be ignited by a small amount of electric power.

Exhaust gas cleaning device for diesel engine

A carbon particulates cleaning device comprises a carbon particulates catching means, a fuel injecting means, a fuel retaining means for retaining the fuel injected by the fuel injecting means near the carbon particulates catching means, a fuel igniting means for igniting the fuel retained by the fuel retaining means, and a gas blowing means which blows gas for maintaining the fuel burning and applying the heat of the burning fuel into the carbon particulates caught by the carbon particulates catching means. The carbon particulates caught by the carbon particulates catching means are effectively burnt and eliminated by supplying gas which is heated due to the burning heat of the fuel ignited by the fuel igniting means.

Carbon particulates cleaning device for diesel engine

A carbon particulates cleaning device for use in a diesel engine of an automobile or the like comprises an exhaust gas main pipe, an exhaust gas branch pipe diverged from the exhaust main pipe, a carbon particulates catching member which is provided within at least one of the exhaust gas main pipe and the exhaust gas branch pipe, a valve means by which exhaust gas is selectively supplied into the exhaust gas main pipe or the exhaust gas branch pipe, a heating means which heats the carbon particulates catching member, a gas supplying means which supplies gas into the carbon particulates catching member when the carbon particulates catching member is heated and a control means which controls each operation of the valve means, the heating means and the gas supplying means. When the carbon particulates caught by the carbon particulates catching member reaches a predetermined volume, a control means operates to stop the exhaust gas from flowing into the carbon particulates catching member, the upper stream portion of the carbon particulates catching member is heated over the burning temperature of carbon particulates by the heating means and gas such as air is supplied from the gas supplying means into the carbon particulates catching member to transmit the heat of the upper stream portion of the carbon particulates catching member into the downstream portion thereof. As a result, the carbon particulates catching member is effectively heated by a small amount of heat energy and the carbon particulates caught by the carbon particulates catching member are burnt and eliminated.
