Abstract
PURPOSE: To make a liquid-employing motion delaying device compact and cheap, by sealing up a liquid in a cylinder with a flexible diaphragm and causing an operating rod to thrust a piston through the diaphragm.
CONSTITUTION: A piston 2, which is recessed and has a perforated hole through the central part, is fitted in a cylinder which has a projection on the bottom. A valve member 4 is provided in the piston 2 to open or close the perforated hole 3. A groove 5 is provided on the peripheral part of the valve member 4 to allow a fluid to pass. A piston rod 6 is fitted in the piston 2 so that the valve member 4 is nipped with play. An operating rod 9 is secured to the piston rod 6 through a diaphragm 8 made of a flexible material such as rubber. The peripheral part of the diaphragm 8 is secured by a cap 10 to the cylinder 1 whose top is recessed. A fluid such as silicone oil is sealed up in the cylinder 1 under the diaphragm 8. The piston 2 is energized upward by a spring 11.
