Abstract: An output shaft is connected to a piston rod of a fluid pressure-driven linear cylinder through a converting mechanism for converting linear thrust of the piston rod into rotational torque and converting operation of the converting mechanism is controlled by operation setting means having a cam groove and a cam follower to thereby causing the output shaft to carry out linear motion and swinging rotation. A driving speed of the piston can be changed by adjusting fluid pressure acting on the piston in a linear motion area and a swinging area of the output shaft respectively.

Abstract: The invention provides a rotary actuator having a cushion mechanism for stopping a vane at a rotational terminal end position in a cushioning manner. The cushion mechanism has a first opening for discharging an exhaust air pressed out from a cylinder hole by a rotating vane to an external portion without limiting a flow amount, a second opening for discharging the exhaust air to the external portion in a state of limiting a flow amount and a flow amount adjusting mechanism for limiting a flow amount, the flow amount adjusting mechanism being connected to the second opening, wherein the first opening is provided at a position sealed by the vane before the vane of a hole surface in the cylinder hole reaches a rotational terminal end position, and the second opening is provided at a position which is not sealed by the vane after the vane reaches the rotational terminal end position.

Abstract: The invention provides a rotary actuator having a rack driven in an oscillating manner by an air pressure, a pinion engaged with the rack, and a cushion mechanism for stopping the rack to at least one normal or inverse stroke end in a cushioning manner. The cushion mechanism has an exhaust port open to a pressure chamber at a position close to a chamber end rather than a port hole, a flow amount adjusting mechanism for restricting a flow amount of the exhaust air discharged from the exhaust port, and a cushion packing mounted to an outer peripheral surface of the piston and operating so as to shut the port hole from the pressure chamber immediately before the piston reaches the stroke end, thereby discharging the air within the pressure chamber through the flow amount adjusting mechanism.
