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.

In a rotary machine having walls forming a compression chamber, input and output openings in said walls, means for regulating the capacity of the chamber comprising means to release a part of the fluid compressed in said chamber, said releasing means comprising a release opening in a wall of the chamber at a point between said input and said output openings, a control slide turnably and slidably mounted in said opening and having passage means connecting said release opening to said input opening, said slide providing varying degrees of communication with the opening in different angular positions of the slide, regulating means controlling the angular position of said slide, and spring means acting on the other side of the slide from the chamber acting on the slide to counteract the pressure of pressure fluid in the chamber.
