Abstract

Hydraulic devices used to control timing, direction, and velocity of fluid flow are disclosed. The hydraulic device includes a flush valve. The flush valve includes one or more venturi that assist in moving the fluid through flush valve. A manifold includes a housing defining a piston cavity and a piston. The piston is moveable within the piston cavity by a piston actuator between a first position and a second position. A manifold inlet defined by the housing is configured to receive a first fluid from a supply line and is in fluid communication with the piston cavity. A manifold outlet is defined by the housing and is in fluid communication with the piston cavity in. In the first position, the piston prevents fluid communication between the manifold inlet and the manifold outlet through the piston cavity. In the second position, the manifold inlet is in fluid communication with the manifold outlet such that the first fluid can flow from the supply line to the manifold outlet through the piston cavity.
