Abstract

A check valve for use in a fluid system such as, for example, a pump. The check valve includes a housing with an inlet, an outlet, and a fluidic chamber formed by an inner wall. The fluidic chamber includes an inlet orifice at a location where fluid flowing from the inlet enters the fluidic chamber. A check ball is disposed with the fluidic chamber of the housing. The check ball is movable between a “closed” position (wherein fluid is prevented from flowing from the outlet to the inlet) and an “open” position (wherein fluid is allowed to flow from the inlet to the outlet). When the check ball is in the open position, the fluid passage formed by the gap between the inner wall and the check ball, has a substantially uniform height.
