Abstract

A valve assembly (35) for pumps (10) is described, comprising:a first chamber (45) adapted to be placed in fluidic communication with an inlet duct (A), a second chamber (50) communicating with the first chamber (45) via a first valve seat (55), the second chamber being adapted to be placed in fluidic communication with an outlet duct (B), 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), a discharge duct (110) communicating with the first chamber via a second valve seat (115), a third chamber (130) communicating with the second chamber (50) and partially delimited by a sliding plunger (140), a second shutter body (125) connected to the plunger (140) and housed in the first chamber (45) where it is movable between a closed position, in which it closes the second valve seat (115), and an open position, in which it opens the second valve seat (115), and a second resilient element (155) adapted to push the second shutter body (125) towards the closed position in contrast to the pressure present in the third chamber (130), an additional chamber (175) at least partially formed in the plunger (140) and placed in fluidic communication with the third chamber (130) by means of an additional valve seat (180), the additional chamber (175) also having an outlet port (215) by means of which it is in fluidic communication with the first chamber (45).
