A refrigerant compressor includes a drive shaft, a pulley fixedly fitted on the drive shaft, over which is passed a torque-transmitting member for transmitting torque from an external drive source to the drive shaft, and a compression rotational member mounted on the drive shaft for rotation in unison with the drive shaft to enable compression of a refrigerant gas. The pulley has a rim in the form of a hollow cylinder, over which is passed the torque-transmitting member, a boss which is fixedly fitted on the drive shaft, and a support member connecting the rim and the boss. A breakaway portion is provided in the support member or the drive shaft for breaking to disconnect the torque-transmitting member from the compression rotational member when a load torque larger than a predetermined value is applied to the breakaway portion. A bearing is arranged on the pulley for receiving tension of the torque-transmitting member to thereby maintain the rim in a rotating state when the torque-transmitting member is disconnected from the compression rotational member by breaking of the breakaway portion.

Rotation speed of automotive auxiliary machines is controlled by a drive pulley provided on a crank shaft and a driven pulley communicating with the drive pulley through a V-belt. The drive pulley comprises a rigid pulley secured on a drive shaft, a guide holder to be rotated together with the drive shaft by a mount bolt, and a slide pulley axially-movably located between the guide holder and the rigid pulley. The slide pulley provides a power piston to be moved along a guide holder shaft. The power piston, the guide holder flange, and the slide pulley define a power piston chamber. Inside of the power piston chamber are located a flyweight to be moved by centrifugal force and a servo valve to be axially moved by the flyweight. The servo valve is fitted on the outer peripheral surface of the power piston. The engine oil, supplied from an oil pan to the drive shaft, is conducted from a mount bolt into a power piston chamber through a power piston and a servo valve and conversely is returned from the power piston chamber to the oil pan through the passage on the outer peripheral surface of the mount bolt depending upon the action of the servo valve.

A connector device for electrically connecting an IC card to a reading and/or writing apparatus. A first guide defining a transport path for the IC card is arranged within a casing having an insertion opening for the IC card. The transport path for the IC card extends from the insertion opening. A second guide extends in inclined relation to the transport path. A contact-probe support is guided by the second guide. The contact-probe support has supported thereon a plurality of contact probes projecting toward the first guide and an elastic arrangement biasing the contact probes toward the first guide. An abutment is associated with the contact-probe support and is arranged in crossing relation to the transport path. As a leading edge of the IC card is abutted against the abutment, the contact-probe support moves together with the IC card, away from the insertion opening and, simultaneously therewith, approaches the IC card under guidance of the second guide, to bring the contact probes into contact respectively with contacts on the IC card.

An electronically controlled fuel injection pump includes a control unit mounted on a pump body and having an internal cooling passage through which a fuel oil flows to cool electronic components of the control unit. On a wall or surface defining part of the cooling passage, there are disposed elongate ribs for preventing the fuel oil from lying stagnant in the cooling passage.

Electronically controlled fuel injection pump

A distributor-type fuel injection pump of the type including a magnetic valve disposed on the head portion of a pump body, wherein a pair of oil seals is disposed on opposite sides of the feed pump, and a bypass passage bypasses the cam chamber and connects a discharge side of the feed pump and an inlet side of the magnetic valve. With this construction, the fuel is delivered without passing through the cam chamber. On the other hand, the lubrication oil is introduced into the cam chamber through clearances between the drive shaft and the bearings and through passageways defined in the drive shaft. The cam assembly or other movable components are lubricated exclusively with the lubrication oil, so that the fuel injection pump operates stably over an extended period of time.

Distributor-type fuel injection pump

A suction space is disposed to selectively communicate with a pump working chamber defined at one end of a plunger via a first communication passageway in which a solenoid valve is arranged, or with suction ports formed in the plunger and communicating with the pump working chamber via a second communication passageway having a restriction therein. The solenoid valve alternately opens and closes for ordinary fuel injection during operation of the engine other than at the start thereof. A selector valve keeps the first communication passageway closed and simultaneously keeps the second communication passageway opened for fuel injection through collaboration of the suction ports with the second communication passageway, in place of the alternate opening and closing of the solenoid valve.

A pair of cut-off ports are formed in a plunger and a plunger barrel at a predetermined axial location and registrable with each other to spill pressurized fuel into a zone under lower pressure. A communication passageway communicates a pump working chamber defined by the plunger at one end thereof with the zone under lower pressure. A solenoid valve is arranged across the communication passageway for blocking same. Control means controls the solenoid valve to cause same to selectively assume an open position and a closed position. While the plunger moves toward the pump working chamber, the solenoid valve is closed by the control means to start injection of fuel present in the pump working chamber, and upon registration of the cut-off ports with each other, the fuel injection is terminated.
