Abstract

PURPOSE: To obtain actions most suitable for the stooping operation of boom of working car at high position, etc., by using a system in which a cylinder is able to operate as a double acting hydraulic cylinder only during the incipient stroke at the beginning of contraction from the end position of expansion of the cylinder.
CONSTITUTION: At the end of the hydraulic cylinder body 1, having the oil supply and discharge connections 2 and 2' leading to an oil pressure generator or an oil tank on its end portion, is provided an oil supply port 3 connected to the connection 2. Also, at the top of the cylinder chamber on the head side is provided an oil discharge port 4 which is connected to said connection 2' through a pipe. The inside of the cylinder chamber 6 is provided with the aperture 11 facing the basic end cylinder chamber on the end of the piston 7 fitted slidably, and also the basic end of the rod 8 is provided with the aperture 12 on a position where it is fitted into the head sliding hole 10 at the expanded end position of the cylinder. And, these apertures 11 and 12 are connected with each other by the through hole 13 to which is provided a check valve 14 by which the flow of oil can be allowed only from the aperture 12 to the aperture 11.
