Abstract
A fluid pressure actuator includes: an actuator body which expands and contracts through supply/discharge of a fluid to generate a driving force; a sensor for detecting a condition of the actuator body; and a control part for controlling a fluid regulator for adjusting a pressure of the fluid supplied to and discharged from the actuator body based on a detection signal from the sensor. The sensor is mounted in the actuator body.
Claims14
A fluid pressure actuator comprising:
- an actuator body which expands and contracts through supply/discharge of a fluid to generate a driving force;
- a sensor for detecting a condition of the actuator body;
- and
- a control part for controlling a fluid regulator for adjusting a pressure of the fluid supplied to and discharged from the actuator body based on a detection signal from the sensor;
- wherein the sensor is mounted in the actuator body;
- and
- wherein the sensor and the control part are provided on a common circuit board, and the circuit board is mounted on the actuator body so that the sensor faces the interior of the actuator body.
