Abstract

Sull'aggancio a forcella (2) di una leva di comando (3) ad azionamento manuale, si impegna un corpo cilindrico o barilotto (1) il quale è dotato di un foro diametrale filettato (4) che si accoppia ad un'estremità filettata (5) di un puntalino (6) il quale comprende anche un tratto intermedio a profilo poligonale (9) che si impegna a scorrimento in una corrispondente boccola (10). La suddetta boccola, comprende un bordo laterale a culla (17) che si sposa col profilo periferico cilindrico di detto barilotto (1) e si impegna a pressione con esso per mezzo di una molla di spinta (14), agente su un interposto anello. L'avvitamento o lo svitamento del puntalino regola la posizione di intervento nei confronti del pistoncino (13) di una pompa di comando e tale posizione viene mantenuta dall'accoppiamento tra la boccola a culla e il barilotto, che si distacca e si ripristina alternativamente in funzione della combinazione dell'avanzamento o dell'arretramento del puntalino, col moto rotatorio derivato dalla filettatura, e del trascinamento in rotazione abbinato allo scorrimento assiale sul corrispondente tratto a profilo poligonale della boccola (10).A cylindrical or barrel body (1) is engaged on the fork coupling (2) of a manually operated control lever (3) which is equipped with a threaded diametrical hole (4) which is coupled to a threaded end (5) of a ferrule (6) which also includes an intermediate section with a polygonal profile (9) which engages by sliding in a corresponding bush (10). The aforesaid bush comprises a lateral cradle edge (17) which fits with the cylindrical peripheral profile of said barrel (1) and engages with it by means of a thrust spring (14), acting on an interposed ring. The screwing or unscrewing of the push rod adjusts the intervention position towards the piston (13) of a control pump and this position is maintained by the coupling between the cradle bushing and the barrel, which detaches and alternatively restores itself in function of the combination of the forward or backward movement of the ferrule, with the rotary motion derived from the threading, and of the rotation dragging combined with the axial sliding on the corresponding polygonal profile section of the bush (10).
