Abstract
A high pressure homogenizer segmentalizes material made of minute solid or the like by passing suspension liquid including the material to a small diameter orifice at high speed under high pressure. An injection valve of the high pressure homogenizer includes: a fixed member having a material introducing passage therein; and a movable member disposed rotatably, swingably, or pulsatingly opposite to the fixed member in an axial direction of the fixed member. The orifice of the injection valve is made of a fine gap in a radial direction disposed between an end face of the fixed member facing an end of the material introducing passage and an end face of the movable member disposed at an end of the movable member opposed to the fixed member. The orifice communicates with a material processing passage via a ring-shaped collision wall.
