Abstract
PURPOSE: To smoothly move the cab of an automobile up and down over its engine with a lifter, by providing the changeover valve of a hydraulic circuit for a cylinder with an intermediate positin to open a pipe passage into the atmosphere.
CONSTITUTION: When a changeover valve 30 is set in a position 3A to move a cab up, pressurized oil from a pump 4 is supplied to the chambers 1c, 1d, of a cylinder 1 to a displace a piston 2 lfetward. To move the cab down after repair work in an engine room or the like, the changeover valve 30 is shifted from the position 3A to another 3B. On the way of the shifting, the valve 30 is passed through an intermediate position 3D which serves to connect a pipe passage 4b to a reservoir 4d so that remaining pressure accumulated in the passage 4b is released into the atmosphere. Remaining pressure in another pipe passage 4b pushes the piston 4p of a check valve 4e downward to help discharge the former remaining pressure out of the pipe passage 4b. After that, the changeover valve 30 is placed in the position 3B to smoothly displace the piston 2 rightward.
