Abstract
A valve and seat set has a seal coupled to the valve body, the seal surface comprising irregularities to allow pressure to propagate in-between the mating surfaces when pressure from the inside of the valve is equal to, or greater than, pressure from the outside of the valve. This allows the seal to lift in response to minimal differential pressure in the intended flow direction (from inside the valve), while effectively sealing pressure in the reverse direction (from outside the valve).
Claims23
A one-way valve, comprising:
- a valve body, the valve body comprising a valve body sidewall and a valve body mating portion for mating with a valve seat;
- a seal coupled to the valve body, the seal comprising:
- a first portion having a seal mating surface comprising a plurality of ribs extending radially outward, the ribs configured to contact the valve seat and form recesses between the ribs that allow for radially extending flow paths, providing greater pressurization of the first portion;
- and
- a second portion comprising a smooth surface for contacting the valve seat;
- and, one or more valve body guides to keep the valve body and seal concentric with the valve seat.

A one-way valve, comprising:
- a valve body;
- a seal comprising at least one portion having surface irregularities configured to form a radial flow path, the seal for mating with a valve seat,
- the surface irregularities allowing for greater pressurization of mating surfaces of the seal and seat.

A one-way valve, comprising:
- a valve body comprising a valve body sidewall and a valve body mating portion for mating with a valve seat;
- a seal coupled to the valve body, the seal comprising:
- a first portion having a seal mating surface comprising irregularities configured to form a radial flow path, the seal mating surface configured to mate with the valve seat, thereby providing greater pressurization of the first portion;
- and
- a second portion comprising a smooth surface for mating with the valve seat;
- and, one or more valve body guides to keep the valve body and seal concentric with the valve seat.
