<p>PURPOSE:To lessen the space for arranging a sequence valve, by slightly protruding an operating rod of the sequence valve into an oil chamber of an oil pressure cylinder and radially mounting the sequence valve. CONSTITUTION:In the vicinity of an end part of the first oil pressure cylinder 1, the point end of an operating rod 37 of a sequence valve 3 is slightly protruded into an oil chamber 11 to mount the sequence valve 3 by aligning its axial line radially to the first oil pressure cylinder 1. While in the end of a piston 12 in the first oil prssure cylinder 1 a tapered part 13 is provided to constitute the piston 12 so as to push up the operating rod 37 with its tapered part 13 immediately before the end of its stroke and communicate the first oil pressure cylinder 1 with the second oil pressure cylinder 2. In this way, as the necessity for width occupied by the sequence valve 3 diametrically of the first oil pressure cylinder 1 is eliminated, an oil pressure cylinder device can be diametrically lessened.</p> |
