Abstract
An apparatus (10) is provided for controlling the flow of a fluid. The apparatus (10) includes a housing (12) having an inlet port (14), an outlet port (16), and a bypass port (18). A throughput block (26) is contained within the housing (12). The throughput block (26) has a number of cylinders (28) formed therein. A number of pistons (34) are received within the cylinders (28). Each piston (34) can move within a corresponding cylinder (28) between a first position and a second position. En the first position, the piston (34) prevents fluid communication between the inlet port (14) and the outlet port (16) and allows fluid communication between the inlet port (14) and the bypass port (18). In the second position, the piston (34) prevents fluid communication between the inlet port (14) and the bypass port (18) and allows fluid communication between the inlet port (14) and the outlet port (16).
