PROBLEM TO BE SOLVED: To reduce capacity flow flowing through a throttle element. SOLUTION: A piston-like throttle element 60 loaded by a spring element 63 is movably guided in a longitudinal guide 61, and forms an annular gap 64 together with the longitudinal guide 61. Seal lengths 65, 67 between the longitudinal guide 61 and the piston-like throttle element 60 are made variable. COPYRIGHT: (C)2003,JPO
