Fluid conveying apparatus for circulating operating liquid in fluid circuits of motor car, has cabinets directly limited together, where fluid exchange between cabinets is optionally enable or not enabled

摘要

The apparatus has two cabinets (1, 3) with two inlets (1a, 3a) and two outlets (1b, 3b), and primary and secondary running wheels (2, 4) rotatably supported on the cabinets. The wheels are acted with fluids from a primary cycle (5) and a secondary cycle (6). The primary wheel is movable in rotation by pressure difference between one of the inlets and outlets, and rotation of the primary wheel is transferred on the secondary wheel. The cabinets are directly limited together, where a fluid exchange between the cabinets is optionally enabled or not enabled.
