The coupling joint, which may be utilized in a valve or the like with the valve body representing one of the tubular members and a bushing representing the other of the tubular members inserted into the open end of the valve body, includes the use of a resilient ring such as an O-ring for retaining the two tubular members together, the ring being positioned in opposed grooves in the telescoped portion of the tubular members.

Abstract: A snap-on, easily removable, fluid shut off valve (with pipe and interlocking member) that is useful as a low cost, primary turn off valve for domestic and commercial fluid fixtures and is quickly installed by manual snap-on between the inlet fluid supply and the supply pipe to conventional fixtures such as faucets or the like. The valve comprises a rigid housing having an inlet chamber and an outlet chamber, and a cross-over passage separating the first and second chambers that houses a moveable ball or poppet valve member that is held in the cross-over chamber by a spring retainer. A mechanical plunger or cam device (operable from the exterior of the housing) is disposed within the outlet chamber for contacting and pushing the ball or poppet valve member against the spring retainer, away from the valve seat, to open the valve.

Abstract: A throttling device is located in a venting pipe or in a pipe section such as a flue gas pipe or conduit arranged between a boiler and a flue or chimney. The flap is held in a pipe section for removal out of the respective pipe either by tilting or by pulling the flap out. For this purpose the pipe section has a slot which is about semicircular and which, in operation, is covered by a ring section or sector. The throttle flap may be pulled out of the pipe section together with the ring section and with its adjustment drive whereby cleaning of the pipe or conduit is substantially facilitated. Heat losses through the flue are avoided when the throttle flap is closed.
