摘要 |
An annular chamber in a housing has inlets at both ends. A central segment of the changer has on its inside wall a groove tapering toward the inside and leading at its base to a centrally located output passageway. Disposed in the groove and central segment of the chamber is an annular gate ring which has a T-shaped radial cross-section. There is sufficient clearance between the ring and the walls to permit the ring to move freely a short distance axially within its confinement. Pressure from one or the other direction of the chamber causes the ring to deform itself against one or the other side of the groove so that the top part of the T-shaped radial cross-section closes off the chamber to the other side. |
