ABSTRACT:
A check valve consisting of two main plastic parts, namely, a valve body member and a cap member which are snapped together to form a valve chamber in which an annular valve seat is formed. A resilient disk in the valve chamber is urged to a seated position on the valve seat by a preload projection on the cap member. The two main parts are formed of a rigid or semi-rigid plastic material which is resilient enough to allow the main parts to yield enough to snap together.
