Taylor, Sr, C O

A pneumatically controlled split cycle cooler utilizes a dual piston compressor in conjunction with a remotely positioned head, the dual pistons are angularly spaced to provide in phase and out of phase pressure pulses for the head; and the head includes a pneumatic piston having an upwardly extending stem to which is attached a displacer/regenerator, a coldfinger, and a pair of pressure volumes spaced above and below the piston by seals and a pneumatic dampening volume between the seals, said pressure volumes operatively connected to the dual pistons for adding and subtracting their pressures in a complementary manner for proper timing and location of the displacer/regenerator and said pneumatic dampening volume operative to provide a pneumatic dampening of the piston to prevent the displacer/regenerator from striking the ends of the cooler and creating audible noise and microphonic inputs to a load to be cooled.
