Abstract: A compression type coupling 10 for pipes has a body member 12 and a fastener member 14 and a ferrule 16 wherein the fastener member has a perpendicular shoulder 36 with respect to a longitudinal axis of the pipe 18 and abuts a squared shoulder section 42 of the ferrule to prevent the ferrule from being squeezed out of the compression coupling 10. The ferrule has outwardly radially extending flanges to retain it within the fastener member. The ferrule also has radially inwardly extending teeth that bite into the pipe to prevent the pipe from backing out. The ferrule also has an axially inner section 40 with notches 62 formed therein. The end 40 is deformed by a camming surface 28 on the body 12 to crimp the pipe 18 as the fastener member 14 is secured to the body member 12. The axially inner section 40 forms a right angled shoulder that abuts the pipe and prevents the pipe from being easily pulled out of the coupling.

Abstract: Three-piece stop valves, in both angle and straight-through forms, are disclosed comprising a valve body, resilient control sleeve and handle, with no separate fasteners or sealing elements being required. The handle and control sleeve are retained within the valve body by resilient formations on the handle which snap into a retaining groove on the valve body. Inlet line pressure resiliently biases the side walls of the control sleeve into sealing engagement with the valve bore to prevent leakage.

Abstract: A simple plastic valve cartridge and faucet valve utilizing a concentric metal pipe having an enlarged bore receiving the valve cartridge. The cartridge includes a cylindrical stationary valve member having an axially off-set inlet bore and an opposed axially projecting peripheral rim portion, a rotatable valve member having an inlet port axially off-set for communication with the port of the stationary valve member and a transverse outlet port, and an annular closure member having an axially projecting peripheral rim portion cooperating with the stationary valve member rim portion to define a cylindrical chamber receiving the rotatable valve member. The valve cartridge thus eliminates the requirement of complex machined metal parts while providing the anti-noise and flow features of the prior art.
