摘要： A steering speed-computing section (81) to differentiate a steering angle of a steering wheel from a steering angle sensor (18) to compute the steering speed signal, a low-pass filter (82) to cut high frequency components in the steering speed signal to output a correction steering speed signal, a switching section (87) to switch the cut-off frequency in the low-pass filter to be higher at the time of determining a high-speed steering condition, and a flow quantity-computing section (85) to compute a target flow quantity supplied to a power steering output section (8) based on the steering angle signal and the correction steering speed signal are provided to control a flow quantity of an operating oil supplied to the power steering output section (8) for the target flow quantity.

摘要： A spool bore (4) where a spool (6) slides, a concave portion (23) opened to the spool bore (4) and facing a return port 12 opened to the spool bore (4), and a land portion (11) disposed in an outer periphery of the spool (6) are provided. A width of the concave portion (23) and a width of the return port (12) each are greater than a width of the land portion (11) and a groove bottom (23a) of the concave portion (23) is formed to be a flat plane generally in proportion to an axis line of the spool (6).
