A component for use in pulse tube cryorefrigerators which integrates the reservoirs (buffer volumes) as well as the housing for the rotary valve and valve plate and drive motor into a convenient, unified assembly. Other components required by the pulse-tube refrigerators, such as the heat sink, orifices, phase shifting valves, connecting tubing, etc., may also be integrated into the buffer volume/valve/motor housing within the teachings of the invention.

1. A cryorefrigeration apparatus of the kind having at least one cooling tube, a oscillation controller coupled to a cooling gas supply and exhaust to generate an oscillating compression-expansion cycle, at least one reservoir to contain an expanding cryogen gas, at least one orifice for the movement and phasing of the gas to and from the reservoir, and a regenerator for absorbing heat temporarily and reversibly, comprising:an integrated pressure oscillation controller and buffer volume housing coupled to the at least one cooling tube, the regenerator, and the cooling gas supply and exhaust, comprising a body having a chamber therein containing the pressure oscillation controller and at least one other chamber forming the at least one reservoir.
