Abstract

A valve assembly (35) for pumps (10) is described, comprising:a first chamber (45) adapted to be placed in fluid communication with an inlet duct, a second chamber (50) communicating with the first chamber (45) via a first valve seat (55), the second chamber (50) being adapted to be placed in fluid communication with an outlet duct, a first shutter body (60) housed in the second chamber (50) and movable between a closed position, in which it closes the first valve seat (55), and an open position, in which it opens the first valve seat (55), a first resilient element (65) adapted to push the first shutter body (60) towards the closed position in contrast to the pressure present in the first chamber (45), an additional chamber (175) in fluid communication with the second chamber (50) via an additional valve seat (180), an additional shutter body (C) housed in the additional chamber 175, where it is movable between a closed position, in which it closes the additional valve seat (180), and an open position, in which it opens the additional valve seat (180), an additional resilient element (185) adapted to push the additional shutter body (C) towards the closed position,wherein the additional shutter is movable, in contrast to the spring force of the additional resilient element (185), from the closed position to the open position if the pressure difference between the second chamber (50) and the additional chamber (175) is greater than a threshold value.
