摘要： A free-piston reciprocating compressor includes a reciprocating piston disposed within a cylinder such that one end of the piston-cylinder provides for a compression space and the other end of the piston-cylinder provides for a balancing space. The piston is coupled to and reciprocatingly driven by the armature of a linear electrodynamic motor, which armature reciprocates on guide means. The compressor also includes porting means operative to establish a stabilizing gradient sufficient to keep the piston operating at a related fixed mid-stroke position. The motor armature is also coupled to a centering-resonance spring.

摘要： The present invention relates to a resonant piston compressor in which a double-sided piston reciprocates within a cylinder and defines a valved compression space on one side of the piston and a balance chamber on its other side. The invention further includes a movable head adjustable between first and second positions to effect a large change in the total volume of the balance chamber between the two positions. In one position, of the movable head an extended balance chamber volume is coupled to the balanced chamber while in the other position of the movable head, the extended balance chamber volume is decoupled from the balance chamber.

摘要： A method and apparatus for controlling a resonant piston compressor of the type comprising an electrodynamic linear reciprocating motor adapted to be driven cyclically by an alternating current power source and having at least one piston coupled to and adapted to be driven within a selectively valved working cylinder by the linear reciprocating motor in synchronism with the frequency of the alternating current power source. Enclosed volumes of gas act as resilient gas springs coacting with the piston and with the linear reciprocating motor to form a mechanical resonant system having a resonant frequency substantially centered on the frequency of the alternating current power source. A midstroke porting arrangement is responsive to the position of the resonant piston for selectively communicating a gas spring control valve with said gas springs. The invention operates to variably control with the gas spring control valve the pressure of the gas in the gas springs to thereby dynamically modulate the stiffness of the resilient gas spring in a manner to control the stroke of the resonant piston compressor within predetermined safe limits. The method and apparatus further include sensing a plurality of different operating parameters of the resonant piston compressor and deriving output sensed signals representative of the respective parameters, combining the sensed parameter output signals to derive therefrom an output control signal and applying the output control signal to the gas spring control valve to variably control the opening and closing of the gas spring control valve.
