Abstract
An apparatus and method for simultaneously setting the stroke and biasing force of a valve assembly, the apparatus utilizes a securement member which individually sets the biasing force of a valve assembly. The stop assembly allows a stop member, for setting the stroke of the valve assembly, and a securement member, for setting the biasing force of the valve assembly, to be secured simultaneously.
Claims30
A method for setting a stroke and a biasing force of a plunger of a valve assembly, comprising:
- a) simultaneously setting the stroke and biasing force of the plunger of the said valve assembly by manipulating the position of a spring and a stop of the valve assembly;
- b) welding said stop to a housing of the valve assembly and welding a retaining member to said stop.
A method for setting the stroke and a biasing force of a valve assembly, comprising:
- applying a device having an outer cylinder and an inner cylinder to said valve assembly, said outer cylinder makes contact with a stop of said valve assembly and adjusts the position of said stop, said inner cylinder makes contact with a retaining member and adjusts the position of said retaining member, wherein said device simultaneously sets the stroke and biasing force of said valve assembly by adjusting the position of said stop and said retaining member;
- and
- welding said stop to a housing and welding said retaining member to said stop.
A valve assembly, comprising:
- a) a valve housing having a valve opening;
- b) a tube being secured to said valve housing at one end and having an opening at the other;
- b) a plunger being configured and dimensioned to be slidably received within said tube, said plunger having a valve end at one end and an engagement surface at the other, said valve end being configured and dimensioned to block said valve opening when said plunger is in a first position;
- c) a stop member being configured and dimensioned to have a portion of said stop member received within said opening of said tube, said stop member having a through opening;
- d) a pin having a stem portion and a head portion, said stem portion being configured and dimension to be received within said through opening of said stop member;
- e) a spring member being received within said through opening of said stop member and making contact with said engagement surface of said plunger at one end and said stem portion at the other;
- f) a securement member being configured, dimensioned and positioned to make contact with said head portion of said pin and a portion of said stop member.

- b) a through opening being positioned in said stop member;
- c) a pin having a stem portion and a head portion, said stem portion being configured and dimensioned to be slidably received within said through opening of said stop member;
- d) a securement member being configured, dimensioned and positioned to make contact with said head portion of said pin and a securement portion of said stop member, said securement portion of said stop member being configured and dimensioned to be slidably received into a portion of said securement member;
- and
- e) a spring being configured and dimensioned to be positioned within said through opening.
3 more elements
A valve assembly, comprising:
- a plunger being configured to be slidably received within said valve assembly for movement between a first position and a second position, said plunger having a valve end at one end and an engagement surface at the other, said valve end being configured and dimensioned to block a valve opening when said plunger is in a first position, said valve end being in a spaced relationship with respect to said valve opening when said plunger is in said second position;
- a stop having a through opening;
- a pin having a stem portion and a head portion, said stem portion being configured to be slidably received within said through opening;
- a spring being received within said through opening of said stop member and making contact with said engagement surface of said plunger at one end and said stem portion at the other;
- and
- a securement member being configured and positioned to make contact with said head portion of said pin and a portion of said stop member.
3 more elements
A stop assembly for use in a valve assembly, comprising:
- a) a stop having a valve assembly contact portion being configured and dimension to be received within said valve assembly;
- b) a through opening being positioned in said stop;
- c) a pin having a stem portion and a head portion, said stem portion being configured and dimensioned to be slidably received within said through opening of said stop;
- d) a securement member being configured to make contact with said head portion of said pin and a securement portion of said stop member, said securement portion of said stop being configured to be slidably received into a portion of said securement member;
- and
- e) a spring positioned within said through opening, said spring making contact with said stem portion at one end and a plunger of said valve assembly at the other.
3 more elements
A method for setting the stroke and biasing force of a plunger of a valve assembly, comprising:
- inserting a stop into said valve assembly, said stop being configured to define a limit of travel of the plunger;
- inserting a pin into said stop, said pin being configured to compress a spring in order to provide a biasing force against the plunger;
- applying a retaining member to said pin, said retaining member limiting the travel of said pin in a first direction;
- and
- adjusting the position of said stop and said retaining member and securing said stop to said valve assembly and said retaining member to said stop.
