摘要： An expander-compressor unit (10) includes a two-stage rotary expansion mechanism (3) having a first cylinder (41) and a second cylinder (42). In the expansion mechanism (3), a suction port (71) facing a working chamber on the upstream side in the first cylinder (41) and a discharge port facing a working chamber on the downstream side in the second cylinder (42) are formed. An intermediate plate (43) is provided between the first cylinder (41) and the second cylinder (42). In the intermediate plate (43), a communication passage (43a) for allowing communication between a working chamber on the downstream side in the first cylinder (41) and a working chamber on the upstream side in the second cylinder (42) is formed. The communication passage (43a) does not communicate with the working chamber in the first cylinder (41) during the suction process, and communicates with the downstream working chamber in the first cylinder (41) at or after the end of the suction process.

摘要： A blending pump assembly for accurately maintaining the proper ratio of two fluid components. Flow of a first fluid is utilized to drive a fluid motor, which in turn drives a pumping mechanism to inject a proportional amount of a second fluid into the flow of the first fluid. The fluid motor and pump are sized so that a predetermined ratio between the two fluids is maintained regardless of changes in pressure and flow rate of such first fluid.

摘要： A counter-rotating 2 cycle piston engine with a combustion chamber and an output shaft rotatably mounted to rotate independently about the same propeller centerline of an aircraft. The Internal combustion power is transmitted to the output shaft by means of a conventional piston, rod, crankshaft configuration journaled to the combustion chamber or engine block in the traditional manner thereby producing concurrent rotation of the shaft and counter-rotation of the engine block. Interior surfaces of the combustion chamber and pistons are angled to control the oil flow inside the crankcase and eliminate unwanted ponding. The pistons are modified to transfer fluid accumulations to the combustion chamber. A throttle is located at the axis of rotation to function normally without the effects of centrifical force. Dual propellers mounted on the shaft and on the block improve thrust performance, balance the torques and moments of inertia of the two counter-rotating masses, All rotational output torque automatically balances itself between counter rotating propellers and is converted into propulsion. No rotational torque is allowed to be transmitted to the airframe through the counter-rotating engine mount.

摘要： The invention relates to motor-driven pumps (1) with turbine, driven by a fluid at high pressure, and more specially intended for the pumping of liquids and of laden liquids. The motor-driven pump (1) according to the invention comprises a rotating sleeve (15) mounted in line between two fixed rings (13, 14). To the internal surface of the sleeve (15) are secured pumping members (31, 32) such as helical vanes. The outer surface of the sleeve (15) forms the rotor of a turbine into which a pressurised fluid is injected radially in a centripetal manner, from a distribution volute (8).

摘要： A rotary input shaft is provided having an axially shiftable cam mounted thereon including circumferentially spaced and axially tapering cam lobes. A pair of reciprocating piston oil pumps are provided and include piston actuating followers engaged with the cam and operable thereby to pump oil through the pumps. An oil turbine is also provided and oil lines extend to and from the turbine from the pumps whereby operation of the pumps will cause oil to be pumped through the turbine which includes a rotary output shaft. By axially shifting the cam on the rotary input shaft the volume of oil pumped by the pumps during each cycle of operation thereof is varied whereby the input of oil to the turbine is similarly varied. The hydraulic system connecting the pumps to the turbine includes oil reservoir means from which oil may be admitted into the working portion of the system and into which oil from the working portion of the system may be withdrawn. Further, structure is provided for expressing oil from the reservoir in response to shifting of the cam to increase the discharge from the pumps and to withdraw oil from the working portion of the hydraulic system into the reservoir in response to shifting of the cam to reduce the output of the pumps. In this manner, even though the amount of oil pumped into and out of the pumps during each cycle of operation thereof varies with the axial shifting of the cam, a closed hydraulic system may be maintained.
