    摘要: Provided is a valve plate of a reciprocating compressor, the reciprocating compressor including a front housing and a rear housing, a cylinder block having a plurality of cylinder bores, a drive shaft rotatably supported by the front housing and the cylinder block, a swash plate connected to the drive shaft to be rotated therewith to vary its inclination angle, pistons reciprocally accommodated in the cylinder bores depending on slide movement of the swash plate, a valve plate installed between one end of the cylinder block and the rear housing and having a suction port and a discharge port, and a suction chamber and a discharge chamber that are formed in the rear housing with the valve plate interposed therebetween, characterized in that an oil suction passage, an oil discharge passage and a coolant supply passage are formed in a surface of the valve plate opposite to the pistons, the oil discharge passage is constituted by at least two branch passages directed from a center part toward an outer periphery of the valve plate, and the branch passages are connected by a connecting passage at the center part. Therefore, it is possible to appropriately distribute the pressure of oil to prevent oil leakage to the coolant supply passage, etc., even when the pressure of the oil discharged through the oil discharge passage is high. Further, the branch passages and the connecting passage have a specific shape to enable smooth flow of the oil.

    摘要: The pressure relief valve has a spring pressure-loaded diaphragm closing body (13), which in the closed position sealingly engages on a centrally positioned valve seating surface (10) surrounding a first valve opening (8). Its spring pressure loading takes place by means of a counterpressure body (13) positioned centrally over it. The valve seating surface (10) is surrounded by a channel-like valve chamber (11) in the valve housing body (2) and on which is provided on the overpressure side at least one second valve opening (9). To be able to dissipate high overpressures, the counterpressure body (30) is surrounded by a diaphragm support ring (17) held on the valve housing (6) and which has a circumferential recess (19), whose depth measured perpendicular to the diaphragm closing body (13) determines the maximum deflection of said body (13), so that when the valve is completely opened the diaphragm closing body (13) is supported in an area between the valve seating surface (10) and its outer edge.
