Abstract
A ball valve comprising a seat having a first opening thereon, a housing over the seat having a second opening defined by a flap having an inner and outer diameter, and a ball in the housing, the ball having a diameter great than the inner diameter of the flap. The seat may be formed directly onto a metal insert of a bonded piston seal, or directly onto a wall of any chamber needing a ball valve therein. The housing may be formed as an extension of a piece of rubber used to seal the periphery of the insert or chamber wall. Hence, the housing and insert or chamber wall may be molded together as part of a unitarily formed chamber and ball valve combination.
Claims27
A ball valve for a bonded piston seal comprising:
- a bonded piston seal insert, the insert having a seat with a first opening thereon;
- a housing over the seat, the housing having a flap at one end, wherein the flap is defined by an outer perimeter and an inner perimeter, the inner perimeter defining a second opening;
- and
- a ball in the housing, the ball larger than the second opening.
A unitarily formed chamber and ball valve comprising:
- a seat formed in a wall of the chamber, the seat having a first opening;
- a housing over the seat, the housing a flap at an end thereof, wherein the flap is defined by an outer perimeter and an inner perimeter, the inner perimeter defining a second opening;
- a ball in the cavity, the ball larger than the second opening;
- and
- wherein the housing is molded to the chamber wall.
A ball valve comprising:
- a seat formed in an insert for a bonded piston seal having a first opening thereon;
- a housing over the seat having side walls wherein the base of the side walls is proximate the seat;
- a ball in the housing;
- and
- a means for retaining the ball in the housing.
A method for creating a ball valve comprising the steps of:
- forming a seat in a dividing member;
- placing a ball over the seat;
- placing a housing over the seat and ball, the housing comprising a flap at an end thereof, wherein the flap is defined by an outer perimeter and an inner perimeter, the inner perimeter defining a second opening smaller than the ball;
- and
- bonding the housing to the dividing member.
A bonded piston seal insert comprising:
- a ball valve comprising
- a seat with a first opening thereon formed in the insert;
- a housing over the seat, the housing having a flap at one end, wherein the flap is defined by an outer perimeter and an inner perimeter, the inner perimeter defining a second opening;
- and
- a ball in the housing, the ball larger than the second opening;
- wherein the housing of the ball valve is molded to the insert.
