Abstract: A wave energy converter comprising a buoyant body and an acceleration tube with a working cylinder and working piston movable therein, a mooring system, and at least one energy collecting device (107) including a differential cylinder (116) having an internal pump piston (117) which is connected to the working piston via a piston rod (118). The differential cylinder (116) comprises a substantially cylindrical pumping chamber (119) on one side of the pump piston (117) and an annular gap-shaped pumping chamber (120) on the other side of the pump piston (117). During a working stroke causing a decrease in volume of the annular gap-shaped pumping chamber (120), the pump piston (117) expels hydraulic fluid (129) from the annular gap-shaped pumping chamber (120) in a direction toward the pressure accumulator (123) and draws hydraulic fluid (129) from the fluid tank (128) into the substantially cylindrical pumping chamber (119). During a working stroke causing a decrease in volume of the substantially cylindrical pumping chamber (119), the pump piston causes hydraulic fluid to bypass the pump piston (117) through a fluid connection from the substantially cylindrical pumping chamber (119) into the annular gap-shaped pumping chamber (120) and further in a direction toward the pressure accumulator (123).

Abstract: An air compressor formed of a plurality of collapsible members engaged between opposing rotating side members. The collapsible members alternate between a collapsed state and enlarged state during rotation around the side members which are engaged to polygonal segments of a generally circular rotating frame. Air compressed in each of said collapsible members during rotation toward the collapsed state is communicated to a reservoir in sealed communication with each of the plurality of between members. The reservoir acts to hold compressed air for use for powering air powered devices.

Abstract: A multi cylinder compressor/expansion engine having a drive shaft that rotates a wobble plate or wedge mounted on the drive shaft. There is a plurality of cylinders in a fixed cylinder barrel with pistons disposed in each of the cylinders. Some of the cylinders are compressor cylinders and some of the cylinders are expansion cylinders. The compressor cylinders discharge a fluid at a first high pressure from the compressor/expansion engine. The expansion cylinders receive fluid at a second high pressure which provides recovered energy which is applied to assist the driver engine or motor thereby reducing the external net energy required for the engine to rotate the drive shaft to do work. Manifold plates and a reed valve assembly operable with the compressor and expansion pistons and ported cylinder sleeves control the flow of fluid into and out of the compressor and expansion cylinders.
