Connector assembly for a gas
First Claim
1. A valve assembly for dispensing a gas into the connector of a gas using device, comprising:
- (a) an outer body with an internal passageway for gas opening through the front end of the outer body, said passageway containing a valve seat and a valve member which is lifted from said valve seat by rearward pressure;
(b) an inner body threaded into said passageway from the front end of the outer body and having an internal opening with which said passageway defines a continuous passage through said assembly;
(c) an axially moveable plunger within said internal opening, said plunger including an activating member adapted to hold the valve member away from the valve seat when the plunger is moved axially in the direction of said outer body, a portion of the plunger having a non-round section complementary to and fitting within a non-round section of the inner body whereby the plunger can be rotated using a suitable tool thereby rotating the inner body and disconnecting said inner body from said outer body, and(d) an opening in said plunger for providing a passage for gas between said passageway and said internal opening when the plunger is moved towards the valve seat.

Abstract
A valve assembly for dispensing a gas, particularly for medical use into a connector of a gas using device, comprising: an outer body with an internal passageway containing a valve seat and a valve member which is lifted from said seat by rearward pressure, an inner body threaded into the passageway of the outer body and having an internal passage and a plunger within said passage which includes an activating member adopted to hold the valve member away from the valve seat when the plunger is moved rearwardly, the plunger and inner body having interlocking parts by which rotation of the plunger requires rotation of the inner body, said inner body has a stepped profile on the outside for mating with a complementary stepped bore in the outer body and a stepped bore on the inside for mating with a hose connector.
