摘要： Each of impeller grooves of an impeller has a first bow surface that extends from one end surface of the impeller so as to have a radius R1, a second bow surface that extends from the other end surface of the impeller so as to have a radius r1, and a projected partition wall having a connecting surface that connects the first and second bow surfaces. A pump cover and a pump base are provided adjacent to the respective end surfaces of the impeller, and are formed with respective annular feed passages that are defined by semicircular wall surfaces having radii R2 and r2, respectively. The radii R1 and r1 of the first and second bow surfaces are set longer than the radii R2 and r2 of the semicircular wall surfaces, respectively.

摘要： An electromagnetic valve is constructed such that lengths of sealing portions, formed by a housing 8 and a spool valve 7 respectively between an input port 8a and a feed-back chamber 11 and between the feed-back chamber 11 and a core 4, are unchanged upon movement of the spool valve; and aligning grooves 15a and 15b are respectively formed between the input port 8a and the feed-back chamber 11 and between the feed-back chamber 11 and the core 4, whereby a smooth and stable pressure is constantly obtainable in response to an applied current even though a supplied pressure is high.
