  • Homogenizing valve
    Patent number: 5887971
    Abstract: In a homogenization unit, a homogenizing valve comprises an impact head which, with a lower valve body, forms an annular high-pressure chamber (64) supplied by a high pressure channel (24). An annular surface of the impact head cooperates with an opposite face of a passage head (22) accommodated in the lower valve body to define a radial passage gap, with an impact ring facing it; the gap leads into a low-pressure annular chamber (54) from which a low pressure channel (34) leads off. The impact head comprises two spaced out guide areas to guide the head in the valve body.
