<p>PURPOSE:To reduce the size of a device by concentrically providing an working fluid guiding body with a valve body on the upper side thereof and respectively providing a supply valve between the working fluid guiding body and a working fluid supply hole and a working fluid exhaust passage on the peripheral side of the valve body. CONSTITUTION:A working fluid guiding body 25 is screwed to the upper recessed groove 32 of a valve body 31. Then, a disk form supply valve 33 is vertically movably provided between the working fluid supply hole 35 of the valve body 31 and the working fluid guiding body 25. Working fluid exhaust passages 47, 49 are provided on the peripheral side of the valve body 31. Thereby, a working fluid supply passage can be arranged in a compact form in the central part of the valve body 31, so that the size of a reciprocating motion switching device of this type can be reduced.</p> |
