ABSTRACT:
In a scroll compression apparatus having an orbiting scroll, a frame with a pressure regulation chamber adjacent the orbiting scroll wherein the frame includes a spring biased annular seal and a pressure responsive device in a discharge aperture through the frame for maintaining constant pressure in the pressure regulation chamber. Preferably, the frame includes an annular groove of rectangular cross-section accommodating a relatively smaller annular seal also of rectangular cross-section. An annular seal spring having a first planar surface and a second planar surface is disposed in the annular channel to bias the annular seal. The pressure responsive device has a first element exposed to discharge fluid pressure and a second element exposed to fluid at suction pressure such that the pressure differential serves to operate a piston for increasing or decreasing the flow area of the discharge aperture from the pressure regulation chamber.
