Abstract: A device that enhances compressor efficiency by reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed by a compression unit. A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a communication port flow guide is provided so as to cover a predetermined area of an opening of a communication port from a side of a flow path in a reverse direction out of two flow paths in different directions around the drive shaft from a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit to the communication port through which the refrigerant flows out. The communication port flow guide transforms a direction of a flow into a direction of a connecting flow path.

Abstract: The present invention relates to a heat engine having a housing. A generally triangular shaped rotor can drive an offset crank as it eccentrically rotates within the housing. Two inlets with valves and two exhausts are provided. The volume between each face of the rotor and the housing defines three expansion chambers. Six power cycles are provided (one by each expansion chamber times two inlets) per revolution of the rotor. Each valve controls the length of time that high pressure gas is allowed to enter each expansion chamber. The valves are controlled by a processor and close when enough pressure is supplied so that the pressures inside and outside the expansion chamber are equal when the chamber is fully expanded just prior to exhaust. Gates can provide a mechanical advantage to the rotor by reducing the amount of pressure applied to the back side of the fulcrum.

Abstract: The present invention relates to an improved rotary engine having one positive motion stroke, the rotary engine comprising at least one of a piston having at least one piston vane. At least one of a unidirectional bearing is operationally coupled to the piston, wherein the piston is configured to allow the piston vane to rotate and the unidirectional bearing prevents the piston vane from rotating during a combustive force or a thrust force injection.

Other exemplary embodiments allow for a secondary exhaust pressure to rotate a piston vane causing the piston vane to self-aligning for the next cycle.

Abstract: An engine configuration that places multiple pistons on one or two oscillating discs. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power.

This engine is especially suited as a driver for electrical power generation as it delivers high torque at low engine speeds, among other uses. Its compact design results in high power to weight ratios.

Abstract: Embodiments of an oil pump for an engine have an increased pump capacity while maintaining or marginally increasing the overall physical size of the pump. In some embodiments, this increased capacity is reflected in a pump length efficiency ratio, which compares an effective gear length (LG) of first and second pump gears used in the oil pump, to an effective housing length (LH). The effective housing length (LH) is a longitudinal distance between surfaces on opposite ends of the oil pump that must be maintained for the oil pump to fit into an available space. Accordingly, the pump length efficiency ratio indicates how much of the effective housing length (LH) can be occupied by the gears. Alternatively, the pump capacity is measured using an output flow efficiency ratio, which compares a theoretical pump flow (FP) at a given gear speed (SG) to the effective housing length (LH) of the pump.

Abstract: The invention comprises a rotary engine method and apparatus configured with a lip seal. A lip seal restricts fuel flow from a fuel compartment to a non-fuel compartment and/or fuel flow between fuel chambers, such as between a reference expansion chamber and any of an engine: rotor, vane, housing, and/or a leading or trailing expansion chamber. In separate states, high pressure and low pressure force sealing movement of the lip seal, respectively. The lip seal is optionally used in combination with a cap seal to form a dynamic seal. The dynamic seals ability to track a noncircular path are particularly beneficial for use in a rotary engine having an offset rotor and with a non-circular inner rotary engine compartment having engine wall cut-outs and/or build-ups. The dynamic sealing forces further provide cap sealing forces over a range of temperatures, pressures, fuel flow rates, varying loads, and operating engine rotation rates.
