Abstract
PURPOSE: To obtain a small and low-cost device capable of turning on and off large power, by providing a switch on an actuator of an oil damper of the device equipped with an oil damper and a spring.
CONSTITUTION: A piston 5 is disigned to move up and down in a cylinder 5 made of plastic, and a spring 7 is pushing the piston 5 upwardly. An actuator 11 is pressed into an indent on the center of the piston 5 through a rubber cap 8a. A cover 9 is brazed by its rim 8b to the cylinder 4 and is made to be airtight by function of the rubber cap 8a. Viscous silicon oil is securely kept in the cylinder 4 in such a manner that its volume is maintained at a constant value even when the piston is moving up and down due to folds 8c and 8d of the rubber cap 8a. While there is no resistance of fluid when the actuator 11 is pushing down, it goes up gradually when it is being pushed up by the spring 7, and a switch 10 linked to the actuator 11 is thus retarded.
