Abstract

A shuttle valve (10) of an oil pump (P) for internal combustion engines. The valve (10) is characterised in that for its shutter (16) it is foreseen on one side a first recess (21) hydraulically communicating with a delivery duct (14) and a second recess (18) hydraulically communicating with a space (23) , communicating in turn with a pressure modulator (24) adapted to modulate the oil pressure within. Furthermore, the first recess (21) and the second recess (18) are hydraulically connected together by means of an orifice (22) present in the shutter (16) .
