Abstract
A reciprocating piston compressor adapted to receive a low pressure gas from an external circuit, and to supply a high pressure gas to the external circuit includes a cylinder block with front and rear ends. The cylinder block includes a central bore extending along the longitudinal axis, and a plurality of axially extending cylinder bores. The central bore has an open end at the front end of the cylinder block and an opposite closed end. Pistons are slidably provided within the cylinder bores for reciprocation. A drive shaft is inserted into the central bore for driving the motion of the reciprocating pistons. A pair of radial bearings, which are provided in the central bore, supports the axially extending drive shaft. An oil separator is provided between the compressor and the external circuit to remove lubricating oil contained in the high pressure gas. An oil reservoir is provided for accumulating the lubricating oil removed from the high pressure gas by the oil separator, the cylinder block including at least a portion of the oil reservoir adjacent to the blind end of the central bore.
