AXIAL PISTON HIGH PRESSURE COMPRESSOR/PUMP

摘要

An axial machine having a wedge that drives a plurality of pistons and a retainer plate for maintaining the slipper shoes in contact with the wedge. A center positioning mechanism for the retainer plate in which the slipper shoes placed on the wedge have a portion extending through a respective hole in the retainer plate, with each of the slipper shoes engaging a point on the side of its respective hole to restrain the retainer plate from movement parallel to the planar angular surface of the wedge. Also described is an oil separation system for removing oil from the gas to be compressed such that the removed oil drains into the oil sump. An oil lubrication system has a cavity around the drive shaft to receive oil from the sump, and disburse the oil through a passageway to discharge ports in the wedge to disburse oil on the planar angular surface of the wedge.

1. In an axial machine having a wedge with a planar angular surface with respect to a plurality of pistons in the axial machine, the wedge in driving engagement with the pistons, a center positioning mechanism for a retainer plate comprising:
a plurality of slipper shoes placed on the planar angular surface of the wedge; each of the plurality of pistons having one end operatively connected to the slipper shoe and the other end slidably received in a cylinder; a retainer plate engaging the slipper shoes for maintaining the slipper shoes in contact with the wedge;
a plurality of holes in the retainer plate with one hole in alignment with and receiving one of the slipper shoes so that each slipper shoe is received in a complementary hole; each of the slipper shoes engaging a point on the side of the respective hole in which the slipper shoe is received with the point of engagement moving around its respective hole as the wedge drives the pistons, the points of engagement on the slipper shoes in their respective holes restraining the retainer plate from movement parallel to the planar angular surface of the wedge.
