Abstract

PURPOSE: To reduce the flowing resistance and the weight and improve response by forming the metering edge of a sleeve into triangular form and obtaining a hollow spool and reducing the step difference between the stem and the rand in the outer peripheral part of the spool.
CONSTITUTION: The metering 3 of a sleeve 1 is formed into triangular form. The spool 4 is formed into hollow form, and the rand 4A with large diameter D and the stem part 4B with small diameter d are formed on the outer diameter. As the spool is formed in hollow form, the spool is lightweight, and its operation is rapid. Fluid flows, turning around the triangular part in the metering edge part 3 of the spool 1, and the flowing resistance is reduced.
