Abstract: A reciprocating piston machine includes a drive shaft having a central axis, a driving element rigidly connected to the drive shaft and extending essentially perpendicular to the central axis, a guide sleeve enclosing the drive shaft and axially displaceable thereon, and a spring element for applying a force to the guide sleeve and which on the one hand is supported on the guide sleeve and which on the other hand introduces forces into the drive shaft. Forces from the spring element are indirectly introduced into the drive shaft.

Abstract: A reciprocating piston engine, particularly a coolant compressor for motor vehicles, includes at least one piston movably supported in a cylinder. A pivot element in the form of a pivot ring is supported on a guide body attached to a shaft in an axially movable fashion such that the pivot element can execute a pivot motion. The pivot motion causes movement of the at least one piston. Spring forces of at least one return spring act on the pivot element in the direction of a start position in which the pivot element is pivoted at a starting pivot angle to a plane on which the rotary axis of the shaft stands upright. At least one further spring element acts on the return spring with an initial tension when the pivot element is in the start position.

Abstract: A stroke-adjustable air conditioning compressor, in particular for motor vehicles, including a drive mechanism for pistons that move back and forth, the pistons being driven by an adjusting plate, such as a pivoting plate, pivoting ring or swash plate at an adjustable pivoting angle. The position of the pivoting angle is influenced inter alia by compressive forces, inertial forces and elastic forces that are active in the drive mechanism.

Abstract: An axial piston machine, especially an air-conditioning compressor for motor vehicles, including a power unit which is rotatably driven by a shaft and in which the rotary movement is converted, via a swash plate, a wobble plate, or a pivot ring, into a fore-and-aft movement of pistons that suction in and compress pressure media. The shaft is mounted in a forward, first axial bearing, among other things.

Abstract: A reciprocating piston machine is proposed, in particular for motor vehicles, comprising a drive shaft (1) having a central axis (5), a driving element (3) which is rigidly connected to the drive shaft (1) and which extends essentially perpendicular to the central axis (5), a guide sleeve (9) which encloses the drive shaft (1) and which is axially displaceable thereon, and a spring element (15) which applies a force to the guide sleeve (9) and which on the one hand is supported on the guide sleeve (9) and which on the other hand introduces forces into the drive shaft (1). The reciprocating piston machine is characterized in that the forces from the spring element (15) are indirectly introduced into the drive shaft (1).

Abstract: A device for coupling a piston to an annular disc, in particular to a captive C-washer/swash plate or to a pivot ring of the working unit of a reciprocating-piston machine, preferably of a compressor of the air-conditioning system of a motor vehicle, having a piston bridge which is assigned to the piston and sliding shoes which are assigned to the annular disc, wherein the piston bridge engages at least partially around or over the annular disc and is in sliding engagement with the annular disc by means of the sliding shoes, is characterized in that the piston bridge is of two-layer design at least on the side facing towards the piston. The invention also relates to a reciprocating-piston machine having a device according to the invention.

Abstract: The invention documents an anti-friction lacquer containing at least one additive (5) that has a polymer matrix distributed within. Additive (5) is subject to change in temperature conditions in a temperature region with an upper threshold of 600° C. for a particular irreversible energy consuming conversion, such as phase change or modification change.

Abstract: An axial piston motor, particularly an air-conditioning compressor for motor vehicles, including at least one piston with an essentially cylindrical piston skirt and with a wrap-around element, which wraps around a swivel ring or a swash plate and a piston slipper that slides on this swivel ring or this swash plate.
