Abstract
The invention relates to a disassemblable cock with which a plug rotatable in the cock housing is releasably latched with the housing. The plug can be moved by tension or pressure from a working position into an intermediate position in which the sealing surfaces of the plug and of the cock housing are located out of bearing yet the plug remains connected to the housing (FIG. 1).
Claims12
A cock comprising:
- a housing having a first sealing surface;
- and
- a plug having a second sealing surface and a longitudinal axis, the plug being detachably mounted at least partially within said housing so as to be movable in an axial direction between a working position and an intermediate rest position, said plug further comprising means for releasably connecting said plug to said housing in a positive and friction fit when said plug is in the working position and in the intermediate rest position so that said plug maintains the position it is in, wherein when said plug is in the working position said first and second sealing surfaces are in contact forming a seal therebetween, and when said plug is in the intermediate rest position said first and second sealing surfaces are not in contact to facilitate rinsing and disinfection of said housing and said cock, said plug being movable out of both of said positions by overcoming the positive and friction fit.
