1. An arrangement, comprising:
a shaft;
two parallel tapered rotating discs mounted on the shaft, wherein each disc is configured to rotate with the shaft, and wherein each portion of a first of the two parallel tapered rotating discs maintains a fixed distance between a corresponding portion of a second of the two parallel tapered rotating discs during rotation of both of the two parallel tapered rotating discs with the shaft;
two outer housings and two outer housing covers, wherein each outer housing combines with an outer housing cover to form a sealed chamber, and wherein one tapered rotating disc is within each sealed chamber;
at least one block arranged in a radial pattern between the two parallel tapered rotating discs; each at least one block having at least one void;
a piston located within each at least one void in each block, each piston configured to translate from a first position to a second position, between the tapered rotating discs;
wherein each block comprises:
a first housing connected to the block, the first housing having a suction side and a discharge side, the first housing configured to channel a fluid;
a second housing connected to the block, the second housing having a suction side and a discharge side, the second housing configured to channel the fluid;
at least a first suction check valve and a first discharge check valve located in the first housing; and
at least a second suction check valve and a second discharge check valve located in the second housing,
wherein the radial pattern is defined as a measured distance away from a center of the shaft and wherein each piston travels between the first housing and the second housing.
