PURPOSE:To prevent the end section of a slide valve from being floated by inserting a guide member into a long hole bored in a valve guide, fixing the other end to the slide valve, and coupling the head section of the guide member with the valve guide. CONSTITUTION:A projection 52 with a narrow width is formed by protruding on a slide valve 21, and the projection 52 is positioned on the cylindrical inner periphery 51 of a valve guide 50 when the slide valve 21 is at the maximum discharge position. A guide member 55 capable of moving along a guide face 54 is inserted into a long hole 53 formed lengthwise in the sliding direction of the slide valve 21, and its one end is fixed to the projection 52 of the slide valve 21, then the head section 56 of the guide member 55 is coupled with the valve guide 50. Thereby, the slide valve 21 is given a turn stop, and its projection 52 is prevented from being floated from the cylindrical inner periphery 51 of the valve guide 50. |
