    摘要: An automotive shock absorber producing a variable damping force. The absorber comprises a cylinder, a piston slidably fitted in the cylinder, two hydraulic chambers partitioned from each other by the piston inside the cylinder, a passage permitting the two chambers to communicate with each other, a rotary valve capable of varying the area of the passage, an acceleration sensor fitted in the cylinder, and an electronic control unit (ECU). The ECU controls the rotary valve according to the acceleration detected by the sensor which includes a vibrating diaphragm and a piezoelectric device.
