Abstract: A hydrostatic bearing lubrication system for a swash plate compressor or engine in which the compressor or engine has at least one reciprocating piston assembly mounted in a cylinder and connected to and reciprocating with a stator in which a rotating and oscillating rotor is mounted. At least one hydrostatic bearing shoe is mounted within the stator in a bearing relationship with the side of the rotor subject to the highest loads in the operation of the compressor or engine.In such a compressor or engine the invention comprises means for continuously varying the pressure of the lubricating fluid delivered to the bearing shoe directly with the load on the bearing shoe. That means comprises a closed cylinder with a free piston carried therein. One end of the closed cylinder on one side of the free piston is interposed in the lubricating fluid pressure line from a constant pressure lubricating fluid pump to the bearing shoe.

Abstract: A wind machine comprising a fixed or controlled pitch blade assembly to drive a variable displacement or variable clearance fluid compressor. Means which may be mechanical, hydraulic, pneumatic or electrical interconnect the blade assembly and the compressor to vary the fluid displacement or clearance volume of the compressor as a function of the drag or lift forces of the wind on the blade assembly.
