Title: Rotary hydraulic actuator
Inventor: YASUDA MASAHARU
IPC: F15B9/09
Filed: 1991-10-21
Abstract: PURPOSE:To cause the exhibition of a fine control resolving power by disposing a reduction gear between the stepping motor and the servo valve in the rotary hydraulic actuator to which the operating angle of the stepping motor is inputted while being controlled. CONSTITUTION:In response to a signal from a controller 2, a stepping motor 1 drives a sun roller 4 of a planetary roller type reduction gear 3 through a specified angle. This causes the rotation of three planetary rollers 5 circumscribed on the sun roller 4. The planetary rollers 5 cause pins 6 to make their self-rotations around an output shaft 8 of the actuator. As a result, a ring 9 is rotated and, due to the cam action thereof, a spool 11 of a servo valve 10 is displaced. This permits an oil pressure to be supplied into a chamber (f) of a hydraulic piston 13, so that a hydraulic port (d) of low-pressure side is opened to permit discharge of the oil pressure in a chamber (e). This causes the hydraulic piston 13 to be displaced to cause rotation of the output shaft 8. This causes the pins 6 to make their rotations around the planetary roller 5 via a crank 14. By the resulting rotation of the ring 9, the spool 11 is returned to its original position to stop the displacement of the hydraulic piston 13.

IPC: B01F15/02
Filed: 1989-10-19
Abstract: PURPOSE: To secure a valve device which opens and close a passage by advancing or retracting a piston, whose front end is inclined, as rotating it. CONSTITUTION: A face 3 of a piston 2 is formed into an incline of about 60 deg.. In addition, when this piston 2 travels between a retracted position and an advanced position, a spiral groove 24 wherein this piston is rotated as far as about 180 degrees, is installed. When compressed air is fed to an air cylinder 11, cylinders 15 and 15' are forcibly pressed forward along a piston supportor 9 by means of thrust rods 14 and 17. At that time, since a roller 19 travels along the spiral groove 24, the piston 2 rotates about 180 deg., and thereby the face 3 closes an opening 5. Thus a valve device which is intermittently opened, is secured in an automatic system or the like for connecting an emptied mixer granulator and fresh materials to be supplied together with each other.
