Beschreibung
Zusammenfassung:	A rotary valve apparatus comprises a rotor housing(2) having an inlet(4) and an outlet(6), a rotor(8) rotatably fitted in the rotor housing(2), a plurality of pockets(22) arranged at regular intervals in the circumferential direction on the outer peripheral surface of the rotor(8) and adapted to be connected successively to the inlet(4) and the outlet(6) of the rotor(8) housing as the rotor(8) rotate, two communication ports(30,38:32,36) arranged in separate regions extending from the inlet(4) to the outlet(6) of the rotor housing(2) and from the outlet(6) to the inlet(4), respectively, with respect to the rotating direction of the rotor(8), and pressure equalizing pipes(42:44) for connecting one communication port(30:32) in one region with the corresponding communication port(38:36) in the other region. As the rotor(8) rotates, the pockets(22U) moving from the inlet(4) toward the outlet(6) and the pockets(22D) moving from the outlet(6) toward the inlet(4) are subjected to two cycles of pressure equalization by means of one and the same equalizing pipe(42:44).
