Abstract: The invention relates to a device for pumping a fluid into a bioreactor. Polsatile pumping is made possible by valve arrangement so that growth of the cells in the bioreactor is increased. Pumping function can be achieved though several mechanisms. A piston can be displaced in a cylinder, especially by an electromagnet, wherein a permanent magnet or likewise an electromagnet can be arranged in the piston. The piston can also be displaced by compressed air. An elastic, hollow body can also be provided, wherein said hollow body can be deformed by mechanical electromagnetic forces so that pumping function is achieved by a change in volume. The pumping device can also be used as implant for assisting or replacing heart function.

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 gas compression apparatus for reciprocating compressor includes: a reciprocating motor generating a linear reciprocal driving force; a compressing cylinder positioned with a predetermined distance from the reciprocating motor; a position controlling cylinder positioned with a predetermined distance from the compressing cylinder; an initial position variable type piston inserted into the compressing cylinder and the position controlling cylinder, and being linearly and reciprocally moved within the compressing cylinder and the position controlling cylinder; and a pressure controlling valve controlling a pressure inside the position controlling cylinder with the pressure of the gas discharged from the discharge chamber. Therefore, the gas compression amount can be controlled by controlling the stroke distance of the initial position variable type piston according to the voltage control of the motor, and at the same time, by controlling the reference position of the initial position variable type piston for the stroke distance of the initial position variable type piston; since the top-clearance of the initial position variable type piston is constantly maintained, the refrigerant gas can be compressed as much as required, an efficiency of the system can be heightened by preventing a refrigerant gas compression loss; and since the dead volume is minimized, an efficiency of the compressor can be improved by preventing a re-expansion loss.

Abstract: A piston support structure of a reciprocating compressor is provided. In the piston support structure, including a piston receiving linear reciprocating driving power generated by a reciprocating motor and being in a linear reciprocating motion in a compression space formed in a cylinder and a first resonant spring and a second resonant spring positioned on both sides of the piston, the first resonant spring and the second resonant spring for elastically supporting the linear reciprocating motion of the piston, the spring constant of the second resonant spring opposite to the first resonant spring is larger than the spring constant of the first resonant spring positioned on the side of the compression space of the cylinder. In the process of the piston being in the linear reciprocating motion between the top dead center and the bottom dead center of the compression space formed in the cylinder, the stress concentration of the second resonant springs for elastically supporting the piston is reduced. Accordingly, it is possible to prevent the endurance of the second resonant springs from deteriorating due to the fatigue of the second resonant springs. Therefore, it is possible to extend the durability of the resonant springs.
