Abstract: An instrument comprises a rotor within a stator. The stator is mounted within a casing which forms a gallery which extends circumferentially around the stator, and an inlet which communicates with the gallery at one end and which projects radially outwardly with respect to the stator from that end. Oblique slots are formed in the stator so that fluid flow to be measured is passed from the gallery to the interior of the stator through them. A barrier in the gallery constrains fluid to flow around the gallery in one direction only.

Abstract: A centrifugal governor for fuel injected internal combustion engines is proposed, especially an idling and final rpm governor for Diesel vehicle engines, in which the sudden emission of smoke upon starting of a heavily loaded engine is prevented. The improved governor comprises an additional idling spring secured on a force transmitting lever which is acted upon by the main control spring and by means of which additional idling spring in the idling setting of the service lever the restoring force of the idling spring on a portion (b) of the idling sleeve path (a) is amplified. This force of the additional idling spring is, however, made at least partially ineffective by a thrust member when the service lever is pivoted into the full-load position.

The reticles are determined transparent for the radiation emmited by an auxiliary laser illuminator modulated according to a modulation different from that provided by the reticles in the passive mode, while the processing and deviation measurement circuits have additional laser signal demodulation circuits and automatic or priority mode selection and switching circuits.

Abstract: A brake booster connected to a dual circuit vehicle brake system includes a housing within which there is located a booster piston and an auxiliary piston interconnected so that the displacement of the auxiliary piston in the direction of the booster piston is communicated to the booster piston. This displacement occurs when the pressure in a reservoir, to which the auxiliary piston is exposed, falls below a predetermined level. The displacement communicated to the booster piston in turn displaces the booster piston to a predetermined position which is located relative to a brake pedal push rod so that the brake pedal push rod can execute an idle stroke.

Abstract: The invention relates to a magnetic valve in which the electromagnet is housed in a chamber which is not infiltrated by the pressure medium to be controlled, and in which a rod coupling is effective between the armature of the electromagnet and the closure body of the valve inserted between a pressure source and a pressure consumer, and in which a sealing apparatus is provided which seals the entryway of the rod coupling into the region infiltrated by pressure medium.

Abstract: A direction finder including downstream the reticle an intermediate objective and a four quadrant detector, the reticle providing a modulation at a given frequency and in which the intermediate objective comprises preferably a half-ball lens whose center of curvature coincides substantially with the detector center to allow a relative movement of the reticle with respect to the detector, such as a rotation round this center controlled by a driving device.

Abstract: Apparatus for measuring the amount of fuel supplied by a fluid supply device wherein a throttle element is inserted in a supply line to a supply device having an apportioning cross-section wherein a constant pressure differential is maintained by means of a pressure comparison device in which the comparison results in an adjustment of the throttle element and whereby the cross-section or the position of the throttle element provides a measurement of the amount of fluid flowing through the supply line which can be transformed into a desirable and useful control value.

Abstract: Cylindrical sleeve having a top portion of enlarged diameter which includes a control bore and which is clamped by an annular screw against a shoulder of a reception bore in the pump housing. An annular screw has, in a widened bore portion at least partially surrounding the top portion of the cylindrical sleeve, a pressure shoulder which is recessed relative to the end face of the annular screw presented to the suction chamber and which transmits the clamping force to the cylindrical sleeve. In a further refinement, the annular screw is provided with an annular extension which surrounds the cylindrical sleeve at a distance therefrom in the region of the control bore and whose inner wall forms a protection against impingement of the jet of fuel emerging from the control bore upon the termination of fuel delivery.

Abstract: A pneumatic diaphragm control member is proposed for a fuel injection device for internal combustion engines, especially for a boost-pressure dependent full-load stop, wherein the initial and end positions of a push rod provided with a control diaphragm and movable against a resetting spring can be varied, and wherein the effective pressure range is variable by means of separate adjusting means which do not affect one another. The push rod of the diaphragm control member contacts, in the unpressurized starting position, a stop screw mounted in the lid cover, and, in the pressurized end position, is in contact, by means of a counter stop attached to an extension of the push rod and adjustable in the direction of motion of the push rod, with a second end stop arranged in the pressure chamber. Thus, the bias of the resetting spring can be changed by changing the position of a bearing bushing for the push rod, which bushing serves as an abutment.

Abstract: An electromagnetic valve for handling fluid media has a valve mechanism which includes at least one valve seat and a valve-closing member which cooperates with the valve seat or seats. The motion of the valve-closing member is controlled by linkage that is connected to the moving arm of an electromagnet, while a return spring urges the armature in the direction opposite to the magnetic force. In order to permit the seating of the armature against a stop at the limit of its energized travel, while exerting a calibrated force on the valve seat, the armature is permitted to travel beyond the point at which the valve-closing member is arrested. The additional motion of the armature takes place against the force of an auxiliary spring which compresses during that part of the motion. When the coil is de-energized, the auxiliary spring urges the armature back into direct contact with the linkage, whereafter the motion transfer is loss-free.

Abstract: The invention relates to a fuel injection nozzle in which a control piston acts on the valve needle, which control piston can also be acted upon by another fluid with an arbitrarily changeable pressure. In this manner it is relatively simple to meet the ever increasing requirements to apply an influence of engine characteristic values to the fuel injection process.

Abstract: The invention relates to a hydraulic brake booster for a vehicle brake apparatus which is provided with a pressurizing apparatus which has a pump and a reservoir. When the reservoir pressure fails, a switchover piston which is subject to the reservoir pressure can disengage a stop for the push rod of the control valve.The push rod is supported on the stop when the pressure supply to the reservoir is intact and after the control valve switches over in the direction of brake activation, in order to give the driver a sense of the added brake force. In the same event, a support of a pedal activation stem on a movable auxiliary cylinder is removed. When the reservoir pressure supply fails, however, this support is made available, in order to enable an immediate mechanical actuation of the main cylinder portion of the brake booster.

Abstract: A pressure control valve for a fuel injection system is proposed which serves to control the warm-up fuel quantity for a mixture-compressing, externally ignited internal combustion engine. The pressure control valve includes a movable valve part which is urged in the closing direction by a compression spring which is counteracted during the warm-up phase by a first temperature-dependent element, whose force on the compression spring below a predetermined temperature in the direction of an increase in the force of the first temperature-dependent element can be influenced by a second temperature-dependent element, so that the fuel-air mixture during the warm-up phase can be adapted to the requirements of every internal combustion engine.

Abstract: An apparatus for controlling the ratio of air to fuel quantity of the operational mixture to be introduced into the combustion chambers of an internal combustion engine which includes an air flow rate meter moving under differential pressure against a constant hydraulic restoring force, which air flow rate meter adjusts a metering cross section in a supply line leading to a fuel injection pump, with the pressure drop at the metering cross section being maintained constant with the aid of a differential pressure valve. The air flow rate meter is part of a known apparatus which controls the fuel component in accordance with the quantity of aspirated air and also controls the component of exhaust gas to be fed back.

Abstract: A method and apparatus for reliably switching electromagnetic control units, especially solenoid valves for blocking the idling fuel mixture in carburetor units of internal combustion engines during, for example, motor vehicle coasting. It is proposed to deenergize the solenoid valve at the beginning of the blocking operation for a time period ensuring a reliable valve release, initiating a current flow which preferably allows the solenoid valve to be at the brink of opening, and, at the desired instant of opening applying an overvoltage to the solenoid valve in a standby position, wherein the valve, though it has not as yet opened, requires merely a small additional pulse to open.

Abstract: An apparatus is proposed for measuring the mass of a fluid medium such as the mass of air induced by internal combustion engines which has at least one temperature-dependent measuring resistor film disposed in the flow of the medium, whose temperature and/or resistance is regulated in accordance with the mass of the medium and wherein the manipulated variable is a measure for the mass of the medium. The temperature-dependent measuring resistor film is disposed on a carrier separated therefrom by an insulating film and a temperature-dependent heating resistor film. The temperature of the heating resistor film is regulated to approximately the same temperature as the temperature-dependent measuring resistor film so that a heat flow between the temperature-dependent measuring resistor and the carrier is prevented. As a result, the response speed of the apparatus to changes in the flow rate of the medium is substantially improved as is the precision of measurement.
