Abstract: A gas compressor includes a compression chamber, an outlet valve, and a shuttle valve which disables the outlet valve when it is connected to an atmospheric pressure relief chamber in idle operation. A throttle line circumventing the shuttle valve is provided which permits by-passed flow between the compression chamber and the atmospheric pressure relief chamber in idle operation, thereby preventing deposits and moisture condensation in the downstream flow path to the pressure relief chamber due to the disabling of the outlet valve, which might otherwise lead to possible operational malfunctions. Compressed-air systems employed in the automotive industry represent an important area of application for the invention.

Abstract: A gas compressor for vehicle braking systems controlled by compressed air can be operated under load or in idle operation. In idle operation, no compressed air is produced. In operation under load, the gas compressor produces compressed air as required by the pressure medium installation. During prolonged operation of the gas compressor at a relatively high operating speed, for example, during travel on super-highways, the power consumption can be decreased and thereby also the production amount of the gas compressor, without having to switch the gas compressor over into idle operation. A clearance volume of less volume than the nominal volume of the gas compressor is provided which can be connected via a valve to the compression chamber of the gas compressor, thereby making it possible to enlarge the compression volume. In addition, a process for the control of the auxiliary valve takes into account different operating magnitudes of the gas compressor and other elements of the vehicle.

Abstract: A compressor with a cylinder head (33, 29) comprises a lower cylinder head section (33) and an upper cylinder head section (29) connected to each other. A seal (12) is provided between the faces of the lower cylinder head section (33) and the upper cylinder head section (29) facing each other. A suction space (31, 25) and a pressure space (10, 17) as well as a suction valve (32, 4) and a pressure valve (5, 7) are installed in the cylinder head (33, 29). A compression space (3) of the compressor is connected by the suction valve (32, 4) to the suction space (31, 25), and by the pressure valve (5, 7) to the pressure space (10, 17). The suction space (31, 25) is also connected by a suction connection (71) to the atmosphere, and the pressure space (10, 17) is connected to a consumer by a pressure connection (18) to a source of pressure.

Abstract: The inventive device produces compressed gas. It is provided with a compressor, wherein the compressor has a compression chamber (25), a suction chamber (10) and a pressure chamber (6). The compression chamber (25) can be connected to the suction chamber (10) via a suction valve (12, 21, 54) and to the pressure chamber (6) via a pressure valve (3). When the receiving-end pressure reaches a predetermined level, the pressure chamber (6) is connected to a compressed-air supply container (44). This connection is via a device for the discontinuation of compressing action (23, 51). In addition, the pressure in the pressure chamber (6) is monitored by a control valve (26), which is a sensing device with a control output (38). The sensing device (26) is designed to produce a control signal at the control output (38), when the pressure in the pressure chamber (6) or compression chamber (25) of the compressor reaches or exceeds a predetermined value.

Abstract: The present invention relates to a gas compressor which prevents noise being produced in the suction conduit during idling. In conventional systems, the noise results from the collision of arriving and returning gas by means of a check valve provided between the suction chamber and the suction conduit. The present invention avoids this noise by providing an additional chamber which is connected via an admixture valve to the compression chamber (20) during the idling operation. This invention is especially applicable to pneumatic systems in automotive technology.

Abstract: A valve vane is provided, where the valve vane is movable along the surface of a casing part and is driven by a dog follower, guided in a slot of the casing part, wherein the slot is furnished at least at one end, and wherein a flat slider is required for a sealing of the casing part. Such a flat slider requires by itself a substantial structure. The invention valve vane (6) is structured such that it covers the slot (12) in each phase of its motion. The invention structure is particularly suitable for being employed in a inlety valve system of a compressor.

Abstract: This invention provides an apparatus for transmitting a driving force between two components. The apparatus utilizes a cover rotatably mounted in a housing such that, as a result of engagement between the cover and a first component, a rotation of the cover corresponds to a displacement of such first component. The first component drives a second component by means of an actuator.

Abstract: A stop apparatus for a plate valve of a fluid compressor is provided. The stop apparatus is equipped with a wear-resistant insert so that the wear on some compressor components can be reduced.
