Abstract: A turbocharger system for supplying charge air to a combustion engine includes a nonventilated hydraulic turbine mounted directly on the turbocharger shaft, and an auxiliary combustor mounted in-line between the engine and the turbocharger. The nonventilated hydraulic turbine is selectively driven by a high pressure hydraulic fluid to drive the turbocharger for supplying air to the auxiliary combustor, which in turn supplementally drives the turbocharger throughout a broad range of engine operation to provide additional air flow to the engine when required.

Abstract: An anti-ice control system for controlling flow of heated air in response to the temperature of the heated air and ambient air.

Abstract: A cooling system for a charge air combustion engine comprising series-mounted heat exchangers for two stage cooling of charge air supplied to the engine. A first stage charge air cooler heat exchanger is coupled into an engine-radiator liquid cooling system in series with the radiator and in parallel with the engine for passage of a portion of the liquid coolant at a first temperature level for first stage cooling of the charge air. A second charge air cooler heat exchanger is supplied with liquid coolant at a second, relatively lower temperature level for second stage cooling of the charge air.

Abstract: A radiant surface combustor comprising a porous combustor element in close heat transfer relation with a heat transfer surface for absorbing radiant heat energy from the combustor element.

Abstract: A heating system which uses bleed air to heat and recirculate cabin air for the passenger space of a vehicle.

Abstract: A charge air cooler for mounting within the intake manifold of a combustion engine. A pair of U-shaped mounting brackets are secured to opposite sides of the charge air cooler, and these brackets carry floating nuts for receiving bolts for mounting the charge air cooler securely within the intake manifold.

Abstract: A centrifugal compressor including a one-piece diffuser ring having a circumferentially extending vaneless diffuser space for receiving compressed gas exiting the compressor impeller, and for guiding the compressed gas to a plurality of outwardly extending and circumferentially arranged diffuser channels each of generally circular cross-section.

Abstract: An absolute pressure relief valve including a venturi and a diaphragm, for limiting the discharge pressure of an aircraft compressor.

Abstract: A fluid motor-pump unit having a circumferentially arranged set of pistons axially reciprocal within a stationary cylinder block, and a rotating valve plate for sequentially porting the pistons between high and low pressure hydraulic ports of an hydraulic system. Apparatus and method are disclosed for dynamically pressure-balancing the rotating valve plate for low friction and low wear operation.

Abstract: A turbocharger system for supplying charge air to a combustion engine includes a nonventilated hydraulic turbine mounted directly on the turbocharger shaft. The nonventilated hydraulic turbine is selectively driven by a high pressure hydraulic fluid to drive supplementally the turbocharger during engine operating conditions when additional air flow to the engine is required.

Abstract: A pneumatic control for turbochargers includes an evaucated bellows-operated servo valve for controlling the pressure differential across a diaphragm, which in turn controls the position of a turbocharger wastegate valve. Discharge pressure from a turbocharger compressor is applied to both sides of the diaphragm. The bellows-operated servo valve is operable to vent one side of the diaphragm whenever the discharge pressure exceeds a predetermined magnitude resulting in a pressure differential across the diaphragm to control the position of the waste gate valve.

Abstract: A system and method for selectively and controllably supplying a preselected pressure source for controlling a pressure-responsive fuel flow metering system, the system being especially capable for use as a Mach number hold unit for controlling fuel flow to aircraft jet engines.

Abstract: A turbine system including a turbine rotatably driven by solar-heated air for driving a load such as an electrical power generator or the like.

Abstract: A radiant surface combustor comprising a porous combustor element in close heat transfer relation with a heat transfer surface for absorbing radiant heat energy from the combustor element.

Abstract: An energy transfer machine including a stator ring carried in a casing forming a toroidal fluid path between a fluid inlet and a fluid outlet.
