A one-way valve is provided. The valve provides a housing with a through hole having an upstream portion and a downstream portion. The upstream portion has a reduced diameter compared to the downstream portion. The housing contains a valve seat. A valve member, or poppet, moves within the through hole from a valve closed position and a valve open position. A low pressure facing side of the poppet engages an elastic member of a compression member that biases the poppet in the valve closed position. A high pressure facing side of the poppet engages a resilient metal seal in the form of an annular disc, which may have a generally wavy or undulating shape. The outer ends of the resilient metal seal are curved to releasably engages the valve seat.
A check valve comprising,
In a check valve having a housing, a valve seat, and a through bore, where the through bore has a first part upstream of the valve seat and a second part downstream of the valve seat, a valve element movable within the housing between a closed position and an open position, and an annular channel extending around the valve seat, an improvement comprising an elastic spring clamp in the annular channel configured to sealingly engage with the valve element when the valve element is in the closed position.
In a one way valve having a housing, a valve seat, and a through bore, where the through bore has a first part upstream of the valve seat and a second part downstream of the valve seat, a valve element movable within the housing between a closed position and an open position, and an annular channel extending around the valve seat, the improvement comprising a metal means for sealing configured to reside in the annular channel and configured to sealingly engage with the valve element when the valve element is in the closed position.
