Abstract:
Improvements in general-purpose valves; wherein liquid flow is controlled by partially rotating a lever arm; the valves comprising a valve body with a fluid inlet placed at the bottom of a head housing chamber as a removable cartridge of an assembly of a corresponding shutter operatively related to an intercommunicating duct from said inlet to an outlet to this chamber; said cartridge-head being removably fitted into said chamber, airtightly fitting on a spandrel above the level of said outlet and on its lower base, around said inlet; characterized in that said fitting is established by means of a complementary cap attached to this base with a central hole that matches both said inlet and the inlet hole of said intercommunicating duct formed on shutter body which is slip inserted into a hole housing said shutter and its actuating spindle; the hole ranges along said head; these elements are assembled to form an assembly axially held against said head, with free turning to shift between closing and opening positions, which are out of phase between each other by, at least, 1/4-turn and determined by cooperative stops of both of them; the shutter being airtightly fitted by its lower end within said cap, while said spindle runs in the opposite direction through sealing means and protrudes from the head lower base and ends in a socket wherein, said lever arm is attached; said intercommunicating duct has an outlet placed on shutter side wall; the outlet is opposite to the surface of said housing-hole of the head, which presents a shutting section for said outlet relative to the closing position of said spindle-shutter assembly; the shutting section is completely encircled by an ""O-ring"" applied in a groove of the wall of said hole, an airtight seal between both surfaces around this outlet is established, said housing hole includes an access mouth to a water trap coming from its outlet, relative to the opening position of the spindle-shutter, said access mouth is formed on the head body and in permanent communication with the outlet of chamber through an opening on the lower base thereof.
