Abstract:
In a cartridge valve comprising a core assembly mounted within a valve body having inlet and outlet ports, the improvement comprising providing structure associated with said core assembly and said body, respectively, whereby said core may be selectively installed in and removed from said body by sequential axial and radial movements of said core with respect to said body; wherein:said core assembly has a proximal end carrying an actuator mechanism and a distal end inserted within a chamber of said valve body; said core assembly includes a first coupling element and said valve body carries a second coupling element, said first and second coupling elements being structured and arranged to provide a bayonet locking attachment of said core assembly within said valve body; said first coupling element comprises a locking groove opening to and is carried by said distal end and said second coupling element comprises a structural element configured to register with said locking groove; and said locking groove is shaped generally as a â€œJâ€  with a long leg opening to said distal end, a transverse connecting leg at a proximal end of said long leg and a shorter leg spaced from said long leg and extending towards said distal end, said core assembly being mounted within said chamber by registering the distal end of said long leg with said structural element, pushing said core assembly until said structural element is positioned within said transverse leg, turning said core assembly until said structural element registers with said shorter leg and causing said core assembly to move outwardly with respect to said chamber, whereby to register said structural element with said shorter leg towards said distal end.
