Abstract

A rotary machine of the sliding vane type has an arrangement for releasing a part of the fluid compressed in the chamber to regulate the capacity of the pressure. This comprises an opening in the wall of the pressure chamber, partially overlying the opening of the cylinder, and a control slide turnably and slidably mounted in the opening. This slide has a passage which is more or less exposed depending on its angular position, the position being controlled by a fluid pressure operated piston. A spring on the opposite side of the control slide from the cylinder pushes the slide toward the cylinder. Under excessive pressure conditions the slide will move away from the wall of the cylinder against the spring and expose the hole of the passage so as to admit full relief of pressure in the chamber.
