A control system, method and apparatus are provided in which a wobble plate assembly is adjustably mounted on a piston and cylinder stroke control assembly. The wobble plate assembly is adjustable through various positions relative to the base, thus providing an adjustable tilt angle to the wobble plate assembly and different strokes for the pumping pistons. In another embodiment the wobble plate assembly is affixed to a clearance volume control assembly, thus providing for simultaneous, independent adjustment of piston stroke and clearance volume of the axial device.

A pump/compressor that utilizes a wedge at a fixed angle to operate the pump's pistons at a fixed stroke. Alternatively the wedge can be moved axially to increase or decrease the clearance volume. Variable fluid flow at any clearance volume is achieved by rotating the wedge with respect to the port plate thereby changing the timing of the pistons with respect to the fixed port plate which changes the timing of the intake and output cycles. This results in a portion of the intake charge being breathed back into the intake port and a portion of the output charge being breathed back from the outlet port. This causes the pistons to not take in a full charge from the inlet port and to not pump out a full charge into the outlet port. Thus, fluid flow is varied. The design results in a smaller pump as the wedge is supported by the pump housing rather than a mechanical linkage required of prior adjustable angle swashplate designs.

A multi cylinder compressor/expansion engine having a centrally mounted drive shaft. A cylinder barrel is mounted on the drive shaft and both the cylinder barrel and the drive shaft rotate about a common axis. There is a plurality of cylinders in the cylinder barrel with pistons disposed in each of the cylinders. Some of the cylinders are compression cylinders and some of the cylinders are expansion cylinders. The compression cylinders discharge a fluid at a first high pressure from the engine. The expansion cylinders receive fluid at a second pressure which provides energy to the engine thereby reducing the energy required for the engine to rotate the drive shaft.

This invention relates to fluid compression and fluid transfer mechanisms for an axial fluid displacement apparatus. More particularly, it relates to a configuration of a bearing supported wobble plate plus intake and discharge valve mechanisms for a reciprocating piston wobble plate-type refrigerant compressor suitable for use with high pressure COas a working refrigerant.

A pressure pulse cancelling device for use with hydraulic pumps/motors/transformers. There is a variable volume fluid receiving cylinder in fluid communication with the discharge line for receiving a quantity of fluid that equals the actual flow rate less the average flow rate in the pumping cycle. A piston or cam within the variable volume fluid receiving cylinder pumps the quantity of fluid received in the variable volume fluid receiving cylinder back into the discharge line when the actual flow rate is less than the average flow rate in the pumping cycle. A second variable volume fluid receiving cylinder is connected to the inlet line and receives a quantity of fluid that equals the actual flow rate less the average flow rate in the pumping cycle. A piston or cam within the second variable volume fluid receiving cylinder pumps the fluid received in the second cylinder into the inlet line at the proper time when the actual flow rate is less than the average flow rate in the inlet portion of the pumping cycle.

A thermal separator/power generator uses the thermodynamic properties of refrigerant substances to provide supplemental heating, cooling, and power without emitting any additional greenhouse gases to the environment by utilizing waste or unused heat energy. This is accomplished through the combined operation of a Rankine Cycle Generator using a refrigerant, preferably a natural refrigerant such as NH3, as the working fluid, and a CO2 a vapor compression heat pump cycle, also called a Thermal Separator Module. The combined system is called a Thermal Separator/Power Generator. It produces electrical power and simultaneously produces secondary heating and water or air cooling as byproducts. In the combined vapor compression heat pump/Rankine power generator cycle, waste heat from external source(s) are recovered and used for heating in the Rankine power cycle. The CO2 heat pump provides cooling and optional space or process heating in lieu of heat boost efficiency for the Rankine power generator cycle.

A control system, method and apparatus are provided in which a rotatable wedge portion which is solidly mounted on a rotatable base engages piston and cylinder assemblies as the base rotates. The wedge is rotatable through various positions relative to the base, thus providing an adjustable tilt angle and different strokes for the pistons. In another embodiment, the single wedge is replaced by a double wedge assembly.
