Abstract
A refrigerant charge valve for a refrigerant system includes a housing adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough. The housing has a cavity and a passageway fluidly communicating with a refrigerant charge port of the refrigerant system component. The refrigerant charge valve also includes a valve core disposed in the cavity of the housing to open and close the passageway to allow and prevent access to the refrigerant.
Claims18
A refrigerant charge valve for a refrigerant system comprising:
- a housing having a base portion with an aperture extending longitudinally therethough adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough, said housing having a stem portion extending generally perpendicular from said base portion with a cavity extending axially therein and a passageway having an inlet at said cavity and extending to an outlet at said aperture for fluidly communicating with a refrigerant charge port of the refrigerant system component;
- and
- a valve core disposed in said cavity of said housing to open and close said inlet of said passageway and being spaced from the refrigerant system component to allow and prevent access to the refrigerant.
A refrigerant charge valve for a refrigerant system comprising:
- a housing adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough, said housing having a first cavity and a first passageway fluidly communicating with a refrigerant charge port of the refrigerant system component;
- and
- a valve core disposed in said first cavity of said housing to open and close said first passageway to allow and prevent access to the refrigerant;
- and
- wherein said valve core has a second cavity extending axially therein from one end thereof, a second passageway extending axially from said second cavity and a third passageway extending radially therethrough and communicating with said second passageway.
A refrigerant charge valve for a refrigerant system comprising:
- a housing adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough, said housing having a first cavity and a passageway fluidly communicating with a refrigerant charge port of the refrigerant system component;
- and
- a valve core disposed in said first cavity of said housing to open and close said passageway to allow and prevent access to the refrigerant;
- and
- wherein said cap has a second cavity with a seal extending axially into said first cavity to engage said housing.
A refrigerant charge valve for a refrigerant system comprising:
- a housing adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough, said housing having a first cavity and a first passageway fluidly communicating with a refrigerant charge port of the refrigerant system component;
- a valve core disposed in said first cavity of said housing to open and close said first passageway to allow and prevent access to the refrigerant;
- and
- a cap removably secured to said housing and having a second cavity with a seal extending axially into said first cavity to engage said housing.
A refrigerant charge valve for a refrigerant system comprising:
- a housing adapted to receive a refrigerant system component of the refrigerant system having refrigerant flowing therethrough, said housing having a first cavity with sealing seat and a first passageway extending axially from said sealing seat and fluidly communicating with a refrigerant charge port of the refrigerant system component;
- a valve core disposed in said first cavity of said housing to open and close said first passageway to allow and prevent access to the refrigerant;
- and
- said valve core comprising a seat extending axially therefrom to engage and disengage said sealing seat, a second cavity extending axially therein from an end opposite said seat, a second passageway extending axially from said second cavity and a third passageway extending radially therethrough and communicating with said second passageway.
