Abstract: A two stage reciprocating compressor and associated HVAC systems and methods are disclosed. The reciprocating compressor includes a crankshaft having an eccentric crankpin, a reversible motor for rotating the crankshaft in a forward and a reverse direction, and an eccentric, two position cam rotatably mounted over the crankpin. The crankshaft and cam combine to cause the piston to have a first stroke when the motor operates in the forward direction and a second stroke when the motor operates in the reverse direction. The cam and crankpin also include stabilization means to restrict the relative rotation of the cam about the crankpin. A lubrication system is provided to lubricate the engaging surfaces of the crankshaft and cam and between the cam and the bearing surface of the connecting rod. There is also provided a control for selectively operating the motor either in the forward direction at a first power load or in the reverse direction at a reduced second power load. A protector for the motor is also provided. In addition, the application of the reciprocating compressor to both air conditioning and heat pump systems is disclosed.

Abstract: A serial, dual piston high pressure fluid pumping system that overcomes the difficulties of gas in the fluid stream without the need for added mechanical valves or fluid paths. A bubble detection and recovery mechanism monitors compression and decompression volumes of the serially configured dual pump head pump, and the overall system delivery pressure. Bubble detection is effected by sensing a ratio of compression to decompression volume and determining if the ratio exceeds an empirical threshold that suggests the ratio of gas-to-liquid content of eluent or fluid in the system is beyond the pump's ability to accurately meter a solvent mixture. The magnitude of the ratio of compression to decompression volume indicates that either the intake stroke has a bubble or that the eluent has a higher-than-normal gas content. Once a bubble has been detected, recovery is effected by forcing the pump into a very high stroke volume with the compression and decompression stroke limits constrained to obtain the largest delivery stroke compression ratio that will expel a bubble or solvent that has detrimental quantities of gas.

Abstract: An inflator mechanism has a valve adapted to secure with the device to be inflated. A compressor is fluidly coupled with the valve mechanism. The compressor mechanism generates fluid to inflate the device. The compressor mechanism includes a motor to drive a piston, a piston, a piston cylinder, an outlet coupled between the piston cylinder and the valve, and a housing. A biasing spring is positioned in the housing to exert a force on the cylinder. The biasing force maintains the cylinder in a first position when the fluid in the cylinder is at a low pressure. The cylinder moves in the housing against the force of the biasing spring to a second position when the fluid in the cylinder is at a high pressure. A displacement control valve is associated with the cylinder to control the fluid displacement of the compressor. Thus, at low pressure, fluid displacement is high and as pressure in the cylinder increases, the fluid displacement is reduced. A power source is coupled to drive the motor of the compressor.

Abstract: An electric shifting mechanism for a fluid-powered diaphragm pump is provided. The shifting mechanism includes a controller programmed to switch the pump at timed intervals, a solenoid valve and an end of stroke valve. The end of stroke valve translates the pneumatic end of stroke signals generated by the pilot valve into electric signals. The electric signals are then transmitted to the controller. The controller sends timed switch signals to an operator of the solenoid valve. The operator shifts the solenoid valve which transmits a pilot signal generated from the compressed air supply to either the right or the left pilot signal port of the main air valve. The main air valve does not receive pilot signals directly from the pilot valve but, in turn, receives its pilot signals from the solenoid valve which receives signals from the controller. The controller receives end of stroke signals from the end of stroke valve which translates the pneumatic signals generated by the pilot valve into electric signals. The controller than compares the end of stroke signals received from the end of stroke valve with the pre-programmed timed intervals and provides an indication or an alarm if the controller is programmed to shift the pump before the pump reaches the end of its stroke. The solenoid valve and end of stroke valve may be easily incorporated into existing pumps.

Abstract: A compressor (10; 100; 200; 300; 500) with a build-in reciprocating motor, comprises a cylindrical housing (20; 120; 210; 510) with two ends thereof fitted with two opposing electromagnets (30; 130; 230; 530), each has a circular inner pole (36; 136) and a coaxial annular outer pole (34; 134). A free piston (50; 150; 250; 560; 600) is disposed in the housing between the two electromagnets, dividing the interior of the housing into two chambers (I, II). The piston carries permanent magnet (40; 140, 145; 561; 610), providing inner and outer poles (44, 46; 141, 146) which have conical surface portions (43, 49; 141, 146) complementary with the corresponding poles (34, 36; 134, 136) of the electromagnets. Sliding pole pieces (630 and 660) can be used to increase the stroke length and reduce the piston's total weight. Valves (61, 63, 65; 161, 165) are fitted to form one-way flow passage connecting the inlet and the outlet of the compressor. In operation, the complementary surfaces of the electromagnets and the permanent magnets form concentric forces which drive the free piston axially while keeping it magnetically suspended, so as to minimize the frictional resistance to the piston's movement and to reduce its wear to minimum. Buffer mechanisms, including air, spring and/or magnetic cushioning, are formed between the piston and each of the electromagnets to prevent direct physical impact between them. A movable support (280; 580) provides automatic adjustment of piston's stroke length in response to changes of output pressure. A circuit (285, 283, 212, 211, 221) is formed to circulate a lubricant for keeping the piston lubricated. Magnetic coupling arrangement (570, 545, 555) is made to further improve the compressor's energy efficiency. In application, a number of the compressors can be connected in series to build up a high pressure output.

Abstract: In a stroke adjusting device on pumps, in particular proportioning pumps, a hydraulic actuation occurs due to the fact that a hollow shaft, which guides in its interior a sliding shaft, is formed as a hydraulic cylinder, in which the sliding shaft, designed as a double action hydraulic piston, is slidable axially in both directions by means of a hydraulic fluid. Owing to this, the required axial adjusting movement of the sliding shaft is not brought out of the hollow shaft axially to the outside, whereby the two ends of the hollow shaft are kept free for the coupling of several engines or pumps.
