Abstract

PURPOSE: To warm up the whole unit of a cylinder device, by allowing the circuit to link an oil chamber at the piston rod side to an oil chamber at the bottom side and providing open-close means in said circuit, and thereby utilizing the temperature of operating oil at the time of idling operation.
CONSTITUTION: The telescopic motion of a rod 13 of a piston 12 housed in a cylinder main unit 11 is performed by alternately feeding the operating oil to a rod side oil chamber A and bottom side oil chamber B through oil feed and return pipes 16, 17. Here both of the above described oil chambers A, B are communicated by a pipe line 18, in the half way thereof a manually operated valve 19 is provided. While in the cylinder main unit 11 are drilled holes 20, 21 with their openings to each oil chambers A, B respectively. To each of the holes 20, 21 is connected each end part of the pipe line 18 respectively. When the device is used under the atmosphere of low temperature the valve 19 is opened to permit the operating oil to flow passing from the oil chamber A or B to the oil chamber B or A and perform an idling operation to warm up the whole unit of the cylinder.
