摘要： The invention relates to a reciprocating piston motor, particularly a refrigerant compressor (1) for a motor vehicle air-conditioner. Said reciprocating piston motor comprises a motor shaft (2), a number of pistons (4), which are mounted inside a motor casing (3) in a circular manner around the motor shaft (2), and comprises a circular swash plate (5), which is driven by the motor shaft (2) and which acts upon the pistons via a linkage assembly (6). The swash plate is connected in an articulated manner to the motor shaft via a driver (7) provided for transferring the drive forces, and the swash plate is mounted on a sliding body (9) in a manner that permits it to pivot about a hinge axis (8) oriented perpendicular to the motor shaft. According to the invention, the sliding body (9) has a recess (9a), which is open toward the rotation axis (11) of the motor shaft and which at least partially encompasses the driver (7) and/or the sliding body (9), on its inner surface facing the motor shaft (2), encloses a cavity (17) inside of which a discharge line (24, 25) passing through the motor shaft (2) leads. The reciprocating piston motor is to be used in refrigerant compressors for motor vehicles.

摘要： The invention relates to a reciprocating engine, especially a refrigerating agent compressor (1) for the air conditioning system of a motor vehicle, comprising an engine shaft (2), several pistons (4) whose axles are arranged on a cylinder jacket at an equal distance relative to the engine shaft and around said engine shaft, a ring-shaped captive C-washer (5 ) driven by the engine shaft (2) and engaging with the piston by means of an articulation arrangement (6), wherein said articulation arrangement has a receiving element with a spherical shape at least in certain areas, in which at least one sliding element is movably arranged in relation to the assigned piston and the captive C-washer. According to the invention, a power transmitting central point (K) located by approximation on the cylinder jacket of the piston axles is assigned to the articulation arrangement (6), said central point being positioned in front of the corresponding piston axle (12) relative to the sense of rotation of the captive C-washer (5). The invention can be used in refrigerating agent compressors for motor vehicles.

摘要： A collector for the liquid phase of the working medium of an air conditioning system has a first and second connecting branch element (4, 5). One of the connecting branch elements (5) continues into a guide pipe (6) which is guided through the interior of the container (3) of the collector (1). Part of the guide pipe extends through the base area (7) of the container provided for the vertical arrangement and has at least one opening (9) for recirculating collected oil and the liquid phase of the working medium. In order to separate the liquid phase of the working medium of the air conditioning system, a cyclone-type separator device (10) is provided. When it is cross-flown from connecting pipe (4) to (5), the collector acts as a separator device, enabling the separation of liquid phases as a result of the cyclone effect in the cyclone chamber (11). In the opposite direction of flow, it re-circulates the liquid phase present in the collector, including oil, returning it into the circuit flow via the opening.

摘要： Provided is an apparatus for adjusting a top clearance of a reciprocating compressor including: a housing, a cylinder block having a plurality of cylinder bores, pistons reciprocally accommodated in the cylinder bores, a piston drive means for driving the pistons, piston connection shafts connected to the pistons, suction/discharge valves installed opposite to bottoms of the pistons, and a suction chamber and a discharge chamber formed in the housing through the medium of the suction/discharge valves, characterized in that each of the piston connection shafts has a conveyance nut threadedly engaged therearound. Therefore, it is possible to readily and precisely adjust a top clearance between a piston and a valve apparatus of a reciprocating compressor, and a dead volume caused by the top clearance can be minimized depending on characteristics of the valve and piston.

摘要： The piston engine has an annular pivoting disk (6) driven by an engine shaft (5) and is adjustably inclined thereto. Said disk drives adjacent pistons (2) arranged in a peripheral direction and is connected in an articulated manner to a sliding sleeve (21) which is axially guided on the engine shaft (5) and is also connected to a driver (13) which transmits driving force and is located at a distance from said engine shaft (5). The annular shape of the pivoting disk (6) is advantageous in terms of dynamics and production. It enables the driver (13) to engage in a radial bore hole (16) of the pivoting disk in an articulated manner, thus saving space.
