<p><P>PROBLEM TO BE SOLVED: To improve quality while reducing a load on a worker, reducing cost and eliminating the erroneous orientation of the assembling of a weight in a hydraulic control valve installed in the piston of a hydraulic multi-disk clutch with the weight fitted to a valve plate to compensate the centrifugal force of oil in a hydraulic working chamber. <P>SOLUTION: This pressure control valve 50 with the single weight 52 is formed by inserting the weight comprising a flange part 71 and a cylindrical part 72 into the caulking hole of the valve plate 51 through the cylindrical part 72 and caulking the valve plate. The valve plate 51 functions as a leaf spring. The weight is caulked correctly on the lateral centerline of the valve plate 51, and its shape is symmetrical with respect to the centerline. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
