Abstract
PURPOSE: To obtain a small-sized speed reduction device with good efficiency and excellent durability by rotating a drum cam with a pin retained by the feeding nut traveling in the axial direction and by taking out the output power from the drum cam shaft.
CONSTITUTION: A feeding nut 3 and a pin 4 fastened on it travel in the axial direction as the input shaft rotates. As the pin 4 rotates in engagement with an inclined groove 13' in a drum cam 5, coupling of the control shaft of valve to the shaft part 14 of the output shaft 16 makes an automatic operation of opening and closing the valve. Because the pin 4 rotates for a portion corresponding to the length of circular arc of the inclined groove 13, the control shaft of the valve is prevented from overfastening. As the load of the control shaft becomes maximum at the time of the valve opening being at approx. 0°, or 90°, the inclination of the portions 20,22 at inclined groove corresponding to these valve openings shall be set so that the speed reduction ratio increases, and thus the motor is prevented from application of varying load.
