In an arrangement for fastening at least one fluid line to a body, in particular a fuel filter for an internal combustion engine wherein the body has a bore and the fluid line includes a cylindrical connecting piece received and locked in the bore, the connecting piece is configured as a plug-in unit provided with a stop collar bearing against the body when the connecting piece is fully inserted in the receiving bore and a mounting plate is detachably connected to the body and has a portion overlaying the stop collar for locking the connecting piece in the receiving bore when the mounting plate is connected to the body.

Arrangement for fastening a fluid line to a body particularly a fuel

In a Fuel Filter arrangement for an internal combustion engine comprising a prefilter and a main filter mounted to the engine by a filter holder, the filter holder has a recess receiving the prefilter, which forms a plug-in unit removably inserted in the recess and position-locked therein.

Fuel filter arrangement for an internal combustion engine

An emergency shut-off device for an air-compressing internal combustion engine is provided in the filter head of the engine fuel filter for the purpose of shutting off the fuel supply for shutting down the engine when the engine cannot be turned off by the ignition key.

Emergency shut-down arrangement for a diesel engine

A fuel circuit is disclosed for air-compressing injection-type internal combustion engines. The fuel circuit is provided with thermostat-controlled fuel preheating and has a switch-over valve controlled as a function of fuel temperature and a heat exchanger as a combined structural unit. The heat exchanger, through which only fuel flows, protrudes into the cooling water flow of the cooling water duct extending in the cylinder head.

Fuel circuit with thermostat-controlled fuel preheating for preferably

A heatable fuel filter for a motor vehicle engine is provided wherein an electric heating element is positioned between a filter head and filter box. In order to prevent fuel contained in the filter head and fitler box from being discharged to the surroundings when the filter box is changed, the filter box is provided with an element for collecting and containing this fuel. A lid container provided for the filter box is filled by the heating element when the filter box is attached to the filter head and heating element. When the filter box is removed from the heating element and filter head, the volume previously occupied by the heating element becomes available for collecting and containing residual fuel flow from the filter head and heating element. The lid container preferably has a volume greater than the volume of fuel contained in the filter head and the heating element.

Heatable fuel filter for diesel engines

In compact vehicle diesel engines, injection pumps are accessible only with difficulty for the purpose of adjusting a starting time of fuel delivery. An adjusting device is provided which includes an adjusting bolt or screw which may easily be reached from a top side of the engine. The adjusting bolt or screw includes a collar which is adapted to engage in a corresponding annular slot provided in an installation flange of a housing of the fuel-injection pump. A threaded portion of the adjusting bolt or screw is threadably accommodated in a threaded member pivotably fastened to the engine. When the adjusting bolt or screw is turned, the injection pump may be rotatably adjusted while a camshaft of the fuel-injection pump, connected to a timing drive of an internal combustion engine, remains in a previous position, thereby varying the start time of fuel delivery of the fuel-injection pump.

Adjusting device for a fuel-injection pump of an internal combustion

A drive mechanism for a fuel injection pump of an internal combustion engine, wherein a drive sprocket and an injection timer unit are arranged in a crankcase of the engine on a drive shaft connected to the camshaft of the fuel injection pump. The drive shaft is formed by a socket sleeve and is floatingly supported on the camshaft.

Drive mechanism for fuel injection pumps of an internal combustion engine

An idling speed adjusting mechanism for injection pumps in which a pivotal connection for raising the idling rotational speed is adjustable against a spring force by way of an adjusting mechanism arranged externally at the pump housing and adjustable against the spring force. The adjusting mechanism includes an adjusting motor formed in particular by an expansion element which is extensible with a temperature increase in the spring prestress direction. The adjusting motor is connected with the pivotal spring connection by way of an intermediate member displaceable between abutments fixed at the housing. The intermediate member, in turn, is spring-loaded with a temperature increase opposite the extension direction of the adjusting piston of the adjusting motor.

Idling adjusting mechanism for injection pumps, especially for diesel

An injection pump, especially for motor vehicles with a control rack and a centrifugal governor, in which the control rack is adjustable by way of a first vacuum box in dependence on the ignition key position and in which, in the stop position of the ignition key, vacuum is applied to the first vacuum box and the control rack is transferred into its turn-off position; a second temperature-dependent vacuum box adapted to be connected with vacuum is provided, whereby an end position corresponding to the full load position is adapted to be determined for the control rack by way of this second vacuum box above a predetermined engine limit temperature.

Injection pump, especially for motor vehicles

An installation for the metered lubrication of an injection pump flangedly connected to an internal combustion engine, in which the cam shaft is driven by an intermediate gear shaft non-rotatably connected therewith, which is rotatably supported in the crankcase of the internal combustion engine on two slide bearings and which is lubricated from a connection with a lubricating oil channel of the internal combustion engine; at least one of the slide bearings of the intermediate gear shaft is constructed in conjunction with the same as metering device; the metered lubricating oil, after leaving the slide bearing, is supplied by way of a sealed space formed at the connecting place between the cam shaft and the intermediate gear shaft, to a central bore through the cam shaft of the injection pump, from where the lubricating oil reaches the injection pump through a radial bore.

Installation for the metered lubrication of an injection pump flangedly

A filter for liquids with a filter head provided with inlet and outlet channels and with a filter body arranged therebelow which is retained at the filter head by a central threaded connection, and in which the discharge of the liquid takes place centrally; a bolt engaging by means of a thread in the filter body is thereby provided to establish the threaded connection which is in communication by way of a coaxial dead-end bore and a cross bore, on the one hand, with the interior of the filter body and, on the other hand, with the outlet channel in the filter head; a sealing ring is provided between the thread of the bolt and the cross bore which provides a radial seal in the filter head with respect to the bolt bore.
