The present invention relates to a pipe connector assembly and a tire maintenance apparatus having the same. The pipe connector assembly comprises a leak-proof valve, and the leak-proof valve is opened only after a sealed fluid medium path is formed between the pipe connector assembly and the tire valve when the pipe connector assembly is screwed to the tire valve. The present invention advantageously prevents fluid medium leakage at the connection between the pipe connector assembly and the tire valve.

Blast activated quick-disconnect apparatus in cooperation with a quick disconnect device including a two-piece body with a longitudinally movable collar surrounding a portion of each of the two pieces, the collar holding the two pieces together in a first position and separating the two pieces in a second or activated position. The apparatus including mounting apparatus fixedly attaching the quick disconnect device to a vehicle to be protected from physical shock or concussion, a mass affixed to the movable collar of the two-piece body, a spring having one end abutting the mass, and a spring stop formed as one of a portion of the mounting apparatus or a separate component. The spring being designed to provide a bias on the mass that prevents movement of the mass and collar into the activated position during accelerations in a normal use range.

A fluid coupling element includes: a body comprising a rear chamber and an intermediate chamber; a main valve movable to close a main passage between the rear and intermediate chambers; a forward valve movable to close a front orifice of the inner pipe under the action of a first spring a safety valve movable to close a secondary passage through the main valve between the rear and intermediate chambers.

During coupling with a complementary coupling element, the forward valve moves a plunger that opens the safety valve before the main valve is opened. The coupling element includes a second spring, pushing the plunger back toward a forward position in which the main valve and the safety valve are closed, and the plunger abuts forwardly against the main valve or against the safety valve.

A quick coupling assembly includes a first coupling element (10) and a second coupling element (50) that is inserted into the first coupling element. The first coupling element has a coupling body (12) and a valve (20), which define a volume displacement passage. When the second coupling element (50) is inserted, the second coupling element mechanically acts on the valve (20) to expel contaminants from the quick coupling assembly via the volume displacement passage. The valve includes a poppet (22) and a biasing spring (24), and the volume displacement passage includes a leak path (66) defined between the coupling body and the poppet. The poppet has an inward contour (68) that is spaced apart from the coupling body to define the leak path. The poppet has a widened portion (70) that provides a sealing surface when the assembly is fully coupled. The second coupling element (50) mechanically acts on the poppet (22) during insertion to expel the contaminants via the volume displacement passage.

A quick disconnect incorporates a male component (nipple) and a female component (socket) that cooperate to form the fluid tight coupling. The nipple at the mating end includes at the outer surface a stepped end forming first and second diameters that are inserted into the socket. The socket includes first and second sleeves, where only the precise stepped end will fit through the sleeves and open the valve of the coupling. The internal fluid path remains identical across all variations of the stepped end and mating sleeves, and many different variations of the quick disconnect valve can be constructed with only minor changes to the stepped end and sleeves.

A fluid connector for removably joining two lines includes a male element and a complementary female element, which each include a body defining an inner passage and an outer passage, a male drawer, which is axially movable inside the outer passage between an uncoupled position of the connector, where it tightly closes off a distal mouth of the outer passage, and a coupled position, where it does not oppose the passage of fluid in the mouth and wherein the male or female body delimits a connecting passage between the outer passage of the female element and the outer passage of the male element during the coupling of the elements and which connecting passage extends between at least one distal opening and at least one proximal opening, which each emerge in one or the other of the outer passages.
