Abstract
A valve assembly includes a stack of valve members which define a number of annular valve slits between knife-edge valve seats and opposing valve surfaces. The valve members are rings having grooves formed therein to define a low pressure liquid chamber. A ridge between the central hole in each ring and the chamber groove forms the knife edge valve seat. Homogenizing pressure can be controlled by flexing a bearing plate at the end of the stack of valves. Spring elements between the valves bias the valves apart when they are released by the hydraulic valve actuator to enable cleaning of the valve slits.
