Abstract

Improvements are disclosed in a radial piston compressor having pistons reciprocally disposed in the piston spaces of a cylinder block rotatably supported on a stationary shaft. The radial motion of the pistons is controlled by a rotatable guide which is arranged with its axis of rotation eccentrically to the axis of rotation of the cylinder block. The portion of the stationary shaft covered by the cylinder block includes a suction slot and a pressure slot extending along a portion of the circumference of the stationary shaft. Oil for sealing the cylinder block and the stationary shaft is introduced into the gap between the cylinder block and the stationary shaft. Due to the rotation of the cylinder block, the piston spaces are communicated alternatingly with the suction slot and the pressure slot through an opening provided in the bottom of the piston spaces. In order to obtain good sealing of the gap between the cylinder block and the stationary shaft by the oil contained in this gap, the gap is provided with a cross section which decreases from the suction slot toward the pressure slot, the oil being introduced into the gap in the vicinity of the largest gap cross section.
