Abstract: An apparatus for controlling an operation of a reciprocating motor compressor includes a current integrator for integrating an alternating current applied to a motor of the compressor during each one cycle thereof; and a controller for differently controlling a firing angle of a triac during the positive phase and the firing angle of the triac during the negative phase of the AC voltage applied to the motor based on the integrated value of the current. A loss in the motor can be reduced by avoiding presence of a DC component in the current applied to the motor of the compressor.

Abstract: A stabilizing structure for a throw adjusting eccentric cam in a two-stage reciprocating compressor is provided. The compressor includes a block that has at least one cylinder with an associated compression chamber and piston, a crankshaft that includes an eccentric crankpin, and a reversible motor for rotating the crankshaft in a forward and a reverse direction. An eccentric, two position cam is rotatably mounted over the crankpin. The cam rotates to and operates at a first position relative to said crankpin when the motor is running in the forward direction and rotates to and operates at a second position relative to said crankpin when the motor is running in the reverse direction. The combined eccentricities of the crankpin and the cam 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. There is also provided a control for selectively operating the motor either in the forward direction or in the reverse direction.

Abstract: Digital fluid pumps having first and second electromagnetic actuators formed in part by a piston to alternately drive the piston in opposite directions for pumping purposes. The piston motion is intentionally limited so that the electromagnetic actuators may operate with a high flux density to provide an output pressure higher than that obtained with conventional solenoid actuated pumps. The electromagnetic actuator coils are electrically pulsed for each pumping cycle as required to maintain the desired fluid flow and output pressure, with the piston being magnetically latchable at one or both extreme positions between pulses. Alternate embodiments and control methods and systems are disclosed.

Abstract: A reciprocating compressor includes a linear motor having a piston reciprocating inside a cylinder. A cylinder head is provided with suction and discharge orifices. A valve means is mounted inside the cylinder and has an operative position, seated against the discharge orifice. The operative position is defined when the top of the piston is within a certain distance from the cylinder head. The distance is defined, so that, at the end of the compression stroke of the piston, a determined pressure is reached inside the cylinder, and the pressure results in a force on the piston. The force is opposite to a force which is impelling the piston and which is sufficient to interrupt its compression stroke before impacting the cylinder head.
