Abstract: The present disclosure relates to a piston for a piston pump, in particular a piston compressor, including a piston main body and a piston crown valve that includes a lamellar valve plate. The lamellar valve plate is fastened to the piston main body by a collar ring.

Abstract: The present disclosure relates to a compressor having a low-pressure region and a high-pressure region, wherein a lubricant is provided in the low-pressure region in order to lubricate the compressor. A fluid is conveyed from the low-pressure region into the high-pressure region and compressed, wherein a portion of the lubricant with the fluid from the low-pressure region reaches the high-pressure region, and wherein a lubricant separator for separating the lubricant from the fluid/lubricant mixture in the high-pressure region is provided. A lubricant return channel for transporting the separated lubricant from the high-pressure region into the low-pressure region is provided.

Abstract: A sliding cam system for an internal combustion engine includes an adjusting element that has at least three coupling pins. A first coupling pin is arranged in the region of the primary sliding cam element and a second coupling pin is arranged in the region of the first secondary sliding cam element and a third coupling pin is arranged in the region of the second secondary sliding cam element. The coupling pins each cooperate with a shifting gate of the respectively associated sliding cam element such that a movement of a primary sliding cam element initiated by the actuator pin is transmissible to secondary sliding cam elements by the adjusting element. The sliding cam system is designed such that a shifting operation of the first secondary sliding cam element takes place at least partially at the same time as the shifting operation of the second secondary sliding cam element.

Abstract: The present invention relates to a piston-cylinder assembly for a radial piston compressor. The piston-cylinder assembly comprises a drive shaft with a cylindrical eccentric for guiding the movement of the piston to a top dead center position. A cylindrical piston guide ring guides the movement of the piston to a bottom dead center. Both the cylindrical eccentric and the piston guide ring are connected to the piston by means of respective concave/convex contact surfaces for the positive transmission of the forces.

Abstract: The present invention relates to a sliding-cam camshaft assembly for an internal combustion engine, comprising at least a first sliding-cam camshaft with a longitudinal axis and a second sliding-cam camshaft with a longitudinal axis. The first sliding-cam camshaft comprises a support shaft and at least one sliding cam. The sliding-cam comprises a first cam and at least one second cam, and a shift gate. The second sliding-cam camshaft comprises a support shaft and at least one sliding cam. The sliding cam comprises a first cam and at least one second cam, and a shift gate. The first sliding-cam camshaft and the second sliding-cam camshaft are arranged parallel to one another. A transmission means for transmitting the switching state of the sliding-cam of the first sliding-cam camshaft to the sliding-cam of the second sliding-cam camshaft is arranged between the first sliding-cam camshaft and the second sliding-cam camshaft.

Abstract: The present invention concerns a sliding cam system for an internal combustion engine having at least one camshaft, an adjustment element and at least one actuator. The camshaft comprises a carrier shaft with a primary sliding cam element and at least one secondary sliding cam element. Each of the cam elements are arranged so as to be displaceable axially relative to the carrier shaft. Each of the cam elements comprises a shift gate with at least one shift groove. The actuator has at least one actuator pin which engages in the shift groove of the shift gate of the primary sliding cam element according to the necessary switch position of the camshaft. The adjustment element is arranged parallel to a longitudinal axis of the carrier shaft and is axially displaceable in the direction of the longitudinal axis of the carrier shaft and has at least two coupling pins.
