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.

Resilient metal seal for check valve

A one-way valve is provided. The one-way valve may be, for example, a check valve, a relief valve, or the like, which may be in the form of a poppet valve. The valve provides a housing with a through hole. The through hole has 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, which typically has a taper. A poppet, or valve member, moves within the through hole from a valve closed position and a valve open position. The poppet has a high pressure facing side and a low pressure facing side opposite the high pressure facing side. The low pressure facing side of the poppet engages an elastic member of a compression member that biases the poppet in the valve closed position. The high pressure facing side of the poppet engages a resilient metal seal in the form of an annular disc. The annular disc has a generally wavy or undulating shape. The outer ends of the resilient metal seal have a curve or arc shape and provide a seat interface that releasably engages the valve seat.
