Valve or faucet for fluids with mechanical locking device

Abstract

The present invention pertains to a valve or faucet for fluids, comprising a body, a stop valve rotating in said body between a closing position and an opening position, and control means for the rotation of said stop valve, in which the said control means are axially movable between a raised position in which they are locked at an angle to the body of the valve and a lowered position in which they are free to rotate, said means being usually kept in the raised position by an elastic element.

What is claimed is:  
     
         1 . Valve or faucet for fluids, comprising a body, a stop valve rotating in said body between a closing position and an opening position, and control means for the rotation of said stop valve, characterized in that said control means are axially movable between a raised position, in which they are locked at an angle to said body of the valve, and a lowered position, in which they are free to rotate, said means usually being kept in the raised position by an elastic element.  
     
     
         2 . Valve or faucet for fluids in accordance with  claim 1 , in which said control means comprise a first pin joined to said stop valve and a second pin joined at an angle to said first pin and fixed to a throttle or grip lever, said second pin being axially movable in relation to said first pin between the raised locking position and the lowered unlocking position, said elastic element arranged between the two said pins.  
     
     
         3 . Valve or faucet for fluids in accordance with  claim 2 , in which around said second pin is provided a washer locked in a seat provided in said body of the valve, said second pin and said washer being shaped so as to be fixed at an angle when said second pin is in the raised position and released when said second pin is in the lowered position.  
     
     
         4 . Valve or faucet for fluids in accordance with  claim 3 , in which said washer has at least one radial slit, and in which said second pin has a longitudinal wall designed to engage usually in said slit and having a profile that tapers upwards in order to be disengaged from said slit when said pin is moved into the lowered position.  
     
     
         5 . Valve or faucet for fluids in accordance with  claim 4 , in which said washer has two opposed radial slits joined together by opposed circumferential arches, and in which said longitudinal wall of the said second pin has a step in each of its opposed sides that are designed to engage in said slits, said second pin being free to perform a maximum rotation of 90° along said arches when it is moved into the lowered position.  
     
     
         6 . Valve or faucet for fluids in accordance with  claim 5 , in which said longitudinal wall of said second pin extends from a hollow cylindrical base guided on its outside in a circular seat provided in said valve body and shaped on its inside to be joined to and to slide on said first pin.  
     
     
         7 . Valve or faucet for fluids in accordance with  claim 6 , in which said elastic element consists of a helical spring accommodated in an axial seat provided in said first pin and acting on said cylindrical base of said second pin.  
     
     
         8 . Valve or faucet for fluids in accordance with  claim 3 , in which said washer has at least one radial tooth insertable into a corresponding notch provided in said valve body for locking at an angle to same.  
     
     
         9 . Valve or faucet for fluids in accordance with  claim 3 , in which said washer and said pins are kept in their respective seats in the valve body by an elastic ring arranged and locked above said washer.
