アルピストン式流体機械の作動流体分配機構。Multi-cam type radial equipped with a biplane cam installed on the inner surface of the casing, a cylinder block with radially arranged pistons that slide in the radial direction in opposition to the cam, and a port block with ports for fluid inlet and outlet. In a piston type fluid machine, a cylinder block and a port block are fixed to a fixed part so as not to rotate, a casing is coupled to a rotating part of a rotating machine, and a first distributor is provided which is rotated by the casing. A multistage cylindrical surface is formed on the inner surface of the distributor, and a second distribution plate is connected to the cylindrical surface so that it can slide freely in the axial direction and rotate simultaneously. A working fluid distribution mechanism for a multi-cam type radial piston type fluid machine, in which both the distributors are slidably inserted between the sliding surfaces of the cylinder block and the cylinder block.
