Abstract
Embodiments of the invention provide a push valve assembly. The push valve assembly includes a valve piston that is movable within a valve body between a fully opened position and a fully closed position, passing through an intermediate rinsing position, to selectively provide pressurized fluid through flow paths defined by the position of the valve piston.
Claims13
A push valve assembly comprising:
- a valve body having a wall defining an inlet end, an outlet end, and a bore extending therebetween;
- an inlet having a wall defining a passage aligned with the bore, the inlet coupled to the inlet end of the valve body;
- and
- a piston movably received within the valve body and the inlet, and configured to selectively restrict fluid communication between the passage and the bore by engaging the inlet, the piston movable between a first position where the bore and the passage are not in fluid communication, a second position where the bore and the passage are in fluid communication, and a third position where the bore and the passage are not in fluid communication and the passage and a piston interior are in fluid communication.

A push valve assembly comprising:
- a body extending from an inlet end to an outlet end, the body defining a bore between the inlet end and the outlet end;
- an inlet proximate the inlet end of the body and extending from an intake end to a discharge end, the inlet defining a passage between the intake end and the discharge end;
- a piston moveable within the bore and the passage, the piston defining an interior between an opening and an outlet;
- a recess defined between the body and the piston;
- a primary flow path defined through the passage of the inlet and the interior of the piston;
- and
- a secondary flow path defined between the passage of the inlet and the recess between the body and the piston;
- wherein a position of the piston relative to the inlet defines:
- a closed position in which the piston inhibits respective fluid communication through both the primary flow path and the secondary flow path;
- a transitional position in which the piston permits respective fluid communication through both the primary flow path and the secondary flow path;
- and
- an opened position in which the piston permits fluid communication through the primary flow path and inhibits fluid communication through the secondary flow path.
