Abstract
A check valve selectively prevents and allows fluid flow between an inlet and an outlet. An elongated housing has an internal fluid passage extending between the inlet and the outlet. The passage is defined in part by at least one sidewall extending parallel to a longitudinal axis of the housing. At least one stationary intermediate aperture is disposed between the inlet and the outlet. A reciprocal member is slidably received within the passage and carries a valve seat engageable with the housing to substantially close the intermediate aperture when in the first position and to substantially open the intermediate aperture when in a second position. The fluid flow passes straight through the reciprocal member along a linear path when the valve seat is moved away from the intermediate aperture. The check valve can be placed between an air pump and a manifold to prevent backflow of fluid from the manifold to the air pump.
