Abstract
The invention relates to a radial piston type pump comprising a casing, a shaft, two or more piston carriers mounted on and driven by the shaft, and a curved track surrounding the piston carriers. The piston carriers are axially movable on the shaft and pressure chamber and scaling means are provided between adjacent carriers to bias them in opposite directions against the internal casing walls which form a chamber in which the carriers are rotatably mounted. Fluid inlet and outlet means in one of these casing walls has fluid communication with the inlet and outlet passages in the carriers and the biasing of a carrier against this wall serves to provide sealing between the relatively rotating surfaces to minimize the leaking of fluid between these surfaces.
