Abstract

A homogenizer valve (1) comprising a ring-shaped first chamber (5) with an inlet (8) for receiving fluid under high pressure, a second ring-shaped chamber (7) with an outlet (9) for fluid under low pressure, a passage head (10) and, between the first and the second chamber, an impact head (11) which is axially mobile with respect to the passage head (10) and acts together with it to define a gap between the impact head (11) and the passage head (10) forming a passage (14) for the fluid passing from the first chamber to the second chamber, and a pusher (15) acting on the impact head (11) to push it in an axial direction towards the passage head (10) thus partially counteracting the pressure exerted by the fluid contained in the first chamber (5) on the annular surface (13) of the impact head (11), this passage (14) comprising at least a first portion (20) and a second portion (21) positioned in sequence between the first chamber and the second chamber, and where the first portion faces in a radial direction and the second portion faces in a direction with an axial component.
