Abstract
A pressure regulator including a closure resisting mechanism that increases the total closure resisting force of a closure element to prevent the closure element from moving into a closed position until a predetermined pressure set point is reached. The closure resisting mechanism operates automatically and is spring actuated in response to pressure within a fluid pathway of the regulator. The closure resisting mechanism is disposed external to the fluid pathway so as not to impede fluid flow.
Claims19
A hose end pressure regulator, comprising:
- a pipe defining a fluid pathway between a fluid inlet and a fluid outlet;
- a closure mechanism including a seat within the pipe and a closure element movable between a biased open position spaced apart from the seat that permits fluid to flow through the fluid outlet and a closed position against the seat to inhibit or prevent the flow of fluid through the fluid outlet;
- and
- a closure resisting mechanism disposed outside of the fluid pathway that applies a closure resistance force to the closure element to prevent the closure element from moving into the closed position against the seat until a predetermined fluid pressure set point is reached;
- wherein the closure resisting mechanism includes a collapse ring having free ends that are spaced apart from one another when the closure element is in an open position and moved towards one another as the closure element moves towards the closed position.

A hose end pressure regulator, comprising:
- a pipe defining a fluid pathway between a fluid inlet and a fluid outlet;
- a closure mechanism including a seat within the pipe and a closure element configured as a hollow tubular piston at least partially defining the fluid pathway and movable between a main spring biased open position spaced apart from the seat that permits fluid to flow through the fluid outlet and a closed position against the seat to inhibit or prevent the flow of fluid through the fluid outlet;
- and
- a closure resisting mechanism disposed between the pipe and the closure mechanism and outside of the fluid pathway, including a sleeve mechanism coupled to the closure element and a secondary holding spring associated with the sleeve mechanism that applies an additional linear a closure resistance force to the closure element in a direction of the force of the main spring when the closure element is in an open position to prevent the closure element from moving into the closed position against the seat until a predetermined fluid pressure set point is reached;
- wherein the pipe is comprised of a hose adapter portion at one end, a nozzle adapter portion at an opposite end, and a tube portion and a bulb portion disposed between the hose adapter portion and nozzle adapter portion;
- and
- wherein the closure resisting mechanism includes a collapse ring having free ends that are spaced apart from one another when the closure element is in an open position and moved towards one another as the closure element moves towards the closed position.

A hose end pressure regulator, comprising:
- a pipe defining a fluid pathway between a fluid inlet and a fluid outlet;
- a closure mechanism including a seat within the pipe and a closure element comprising a hollow tubular piston at least partially defining the fluid pathway and movable between a main spring biased open position spaced apart from the seat that permits fluid to flow through the fluid outlet and a closed position against the seat to inhibit or prevent the flow of fluid through the fluid outlet;
- and
- a closure resisting mechanism disposed between the pipe and the closure mechanism and outside of the fluid pathway;
- wherein the closure resisting mechanism includes a secondary holding spring that applies an additional linear closure resistance force to the closure element in a direction of the force of the main spring when the closure element is in an open position;
- wherein the closure resisting mechanism includes a collapse ring, the collapse ring having free ends spaced apart from one another when disposed within a first diameter portion of a tube, the free ends moved towards one another as the collapse ring moves linearly to a second portion of the tube of smaller diameter as the closure element moves towards a closed position;
- and
- wherein the collapse ring and the secondary holding spring cooperate with the main spring to prevent the closure element from moving into the closed position against the seat until a predetermined fluid pressure set point is reached.
