Abstract

PURPOSE:To reduce dispersion of operation and improve productivity of an oil dash pot by using a spring only for keeping a plunger away from the adsorbing condition such that time lag characteristics are given by attracting force, viscous resistance and stroke. CONSTITUTION:An oil dash pot has a vertical type cylinder 1 openened at the upper end and filled with viscous material 2. The cylinder 1 also has a plunger 3 loose fitted therein and dropped to the bottom by its own weight. A coil spring 5 having a predetermined dimension smaller than a distance between the opening of the cylinder and the upper end of the plunger 3 is mounted on a small diameter projection 4 thereof, and a pole head 6 is mounted on the upper opening of the cylinder 1 to close the cylinder. While a coil frame 8 wound by a coil 7 is mounted around the outer periphery of the cylinder 1, an horizontal leg 9a of an L-shaped yoke 9 having a hole through which the cylinder 1 is inserted is located beneath the coil frame 8 and a movable iron piece 10 is mounted pivotably on the upper end of a vertical portion 9b of the yoke 9.
