Abstract
A quick connection coupling valve assembly having a poppet member in both a male coupling member and female coupling member, a fluid passageway defined therethrough is opened by engaging the poppet members of the male and female coupling members with each other, the fluid passageway is closed by releasing a spring member to disengage the poppet members from each other. A plurality of longitudinal stops are disposed on an inside wall of the male and female coupling members. The stops limit movement of the poppet members.
Claims12
A quick connection coupling valve assembly, comprising:
- a male coupling member having a front end and a back end, the male coupling member including a housing which reciprocally receives a first poppet member therein and defines a fluid passageway therethrough, the first poppet member being axially movable between an open position and a closed position, the first poppet member having a tip end normally projecting from a front end of the housing when in the closed position, a spring member being compressedly disposed between a back end of the housing and the first poppet member to bias the first poppet member into the closed position, the back end of the male coupling member being connectable to a fluid conduit;
- a female coupling member having a front end and a back end, the female coupling member including a housing defining a fluid passageway therethrough having first and second housing portions, the first housing portion reciprocally receiving a second poppet member and the second housing portion receiving the first end of the male coupling member, the second poppet member being axially movable between an open position and a closed position, said second poppet member having a tip end normally projecting from a front end of the first housing portion when in the closed position, a spring member being compressedly disposed between a back end of the first housing portion and the second poppet member to bias the second poppet member into the closed position, the back end of the female coupling member being connectable to a fluid conduit;
- a first o-ring is disposed on an outer surface at a front end of the first poppet member and forms a fluid tight seal between the first poppet member and the male coupling housing when the male coupling member is disengaged from the female coupling member;
- a second o-ring is disposed on an outer surface at a front end of the second poppet member and forms a fluid tight seal between the second poppet member and the female coupling housing when the male coupling member is disengaged from the female coupling member;
- the first and second o-rings forming a maximum diameter at the tip end of the first and second poppet members over which fluid flow is guided;
- and
- clip means proximate the front end of the female coupling member for releasably locking the male coupling member in the female coupling member.
