摘要： A reciprocating-piston uniflow engine includes a harmonic oscillator inlet valve capable of oscillating at a resonant frequency for controlling the flow of working fluid into the engine. In particular, the inlet valve includes an inlet valve head and a spring arranged together as a harmonic oscillator so that the inlet valve head is moveable from an unbiased equilibrium position to a biased closed position occluding an inlet. When released, the inlet valve head undergoes a single oscillation past the equilibrium position to a maximum open position and returns to a biased return position close to the closed position to choke the flow and produce a pressure drop across the inlet valve causing the inlet valve to close. In other embodiments, the harmonic oscillator arrangement of the inlet valve enables the uniflow engine to be reversibly operated as a uniflow compressor.

摘要： A modular air-driven pump includes an air motor and various sized fluid pumps which are interchangeably mountable to the air motor. The air motor includes first and second bulkheads, a motor cylinder held between the first and second bulkheads, and a motor piston within the motor cylinder. An air control system supplies air from an air inlet to the motor cylinder alternately on each side of the motor piston while venting the motor cylinder on an opposite side of the motor piston to an air outlet to reciprocate the motor piston. The first bulkhead has an opening substantially coaxial with the motor cylinder and first and second cylindrically-shaped and coaxial recesses at an outward side of the first bulkhead which surround the opening The second recess has larger diameter and a smaller depth than the first recess so that they are stair stepped. Each of the first and second fluid pumps include an end block, a pump cylinder held between the end block and the first bulkhead coaxial with the motor cylinder and within one of the recesses, and a pump piston within said pump cylinder. The pump piston is removably connected to the motor piston through the opening for reciprocable movement of the pump piston with the motor piston. The pump cylinder of the first fluid pump is sized and shaped for cooperating with the first recess of the first bulkhead and the pump cylinder of the second fluid pump is sized and shaped for cooperating with the second recess of the first bulkhead. An air-motor enclosure surrounds the air motor and a fluid-pump enclosure surrounds the fluid pump. The fluid-pump enclosure forms an exhaust plenum in fluid communication with the air outlet and has an exhaust outlet to reduce noise created by exhausting air.

摘要： A magnetically actuated fluid motor has a shiftable member having valve members for alternately closing one and opening the other of large and smaller faces of a stepped piston reciprocating in a housing. The shiftable member carries a magnet and is shiftable to collocate the magnet with one of spaced apart magnet attractors. A magnetic holding force between the magnet and attractors exceeds a simultaneous resilient counterforce supplied by spring members operating on the shiftable member. When the magnetic holding force is weakened by application of a separating force to separate the magnet from an attractor, stored energy in the compressed springs is released to shift the shiftable member. Separating force is applied through stops which arrest the shiftable member while the piston continues to move, without immediately opening the closed face of the stepped piston. Once the magnet is separated from the nearest magnetic attractor by a pre-shift amount, so that the resilient shifting force exceeds the weakened magnetic holding force, the shiftable member shifts, closing the open face and opening the closed face of the piston to reverse the piston stroke. The magnet carried by the shiftable member operates in a chamber-like area having fluid ports which dampen the shifting action.

摘要： An actuator is driven in a first direction by equal working fluid pressures acting on different piston areas acting in opposite directions, and is driven in a second direction by applying equal pressures on both sides of one of the piston areas. Working fluid from an inlet port, acting in a working fluid chamber, pushes up a valve plate, closes ventilation holes and opens working fluid discharge holes, thereby permitting the working fluid to push the piston upward. Working fluid contained in the working fluid chamber is exhausted from working fluid discharge holes to the outside of the system through a working fluid discharge pipe. When the upward movement of piston reaches its limit, a valve plate is pushed by a spring, thereby causing simultaneous closing of the working fluid discharge holes and the opening of the ventilation holes. As a result of the opened ventilation holes, working fluid pressures in a lower working fluid chamber and an upper working fluid chamber become equal. The working area acting downward is greater than the working area acting upward to generate a net downward force uring the piston downward. The working fluid discharge pipe fluid-tightly fitted through the piston to provide a discharge path of working fluid from the system.

The control valves (2), depending on their position, actuate several control channels (4) leading into severan control pressure chambers (3) so that, depending on the position of the control valves (2), communication can be established between an energy source (5) and s spring-loaded servo piston (6) which, via an adjoining working cylinder (7) sealed by the servo piston (6), delivers a medium of low pressure level to an energy level of high pressure by means of a pressure piston (8), with the servo piston (6) having elastic means (11) which influences a change-over point of the control valves (2) and which, for the purpose of switching the control valves (2), can be clamped in position between a servo element (9) connected on the servo piston (6) and control rod (10) engaging the control unit. The device provides simple, operationally reliable, actuation of the control valves (2). The device of the present invention is particularly useful for automotive vehicle applications.

摘要： A wellhead mounted pneumatic actuator for bottom hole oil pumps designed for operation by compressed air or gas. The preferred embodiment utilizes a single action cylinder with the downstroke actuated by the weight of the sucker rods and the fluid contained therein. Sufficient relatively high pressure air or gas from an external source is supplied under the piston of the cylinder to lift the piston at all times. A pressure or solenoid control floating piston bleeder valve selectively routes air or gas into the power cylinder on both sides of the piston to accomplish the downstroke. First and second contactors are mounted to cables suspended from a spreader reciprocating with the piston to contact respective first and second pivot arms to pivot the pivot arms into engagement with the respective first and second activator buttons of the bleeder valve to shift the bleeder valve from one position to the other to effectuate the selective routing of air or gas to the top of the piston as well as under the piston. The contactors are releasably mounted to the cables for securing at different locations therealong to adjust the length of the stroke of the piston. The actuator also includes an improved seal or packing gland.

摘要： A uniflow engine has a plurality of cylinders disposed symmetrically around a common crankshaft connected to pistons reciprocating in the cylinders. In response to the availability of a working fluid vapor at a predetermined condition, such as a high pressure or temperature, incoming vapor is supplied to those cylinders in which the respective pistons are in their working strokes to thereby initiate rotation of the crankshaft in a predetermined direction regardless of the position in which the crankshaft had stopped last. Once rotation is initiated and a predetermined mode change speed attained in a "start-up mode" by engine operation from start, vapor inlet valves are controlled to change engine operation over to a "running mode". In the "start-up mode" incoming vapor is admitted over a substantial portion of the piston working stroke, whereas in the "running mode" vapor inflow is terminated relatively early in the working stroke so that a vapor change does work in expandiing against the piston.
