Abstract
PURPOSE: To improve detecting accuracy with improvement of responsibility to the pressure by detecting the stop position of a moving stand by a pressure switch with use of Bourdon tubes to actuate by pressure difference in the cylinder.
CONSTITUTION: When a moving stand moves in the left direction until it hits a stopper 8, oil pressure in a chamber (A) in a cylinder 2 becomes almost zero, then oil pressure in a chamber B goes up, and a big pressure difference is generated in the cylinder 2. This pressure difference rises the tip of a Bourdon tube 48 to the highest positin while it send down the tip of a Bourdon tube 46 to the lowest position, a screw 60 comes into cntact with a displacing member 56 to put a switch 68 ON. The control part receives the ON signal from the switch 68 and gives the signal to a solenoid. Thus, it returns and moves a spool 82 in the right direction, sets a direction change-over valve 10 into the neutral condition, and gives exciting signals to the solenoid of the direction change-over valve for the cylinder to move another moving stand.
