POWER PACK HYDRAULIC APPARATUS WITH FEEDBACK CAM HAVING GOOD CONTROL CAPACITY FOR CONTROLLING FLOWING MEDIUM IN WIND POWER PLANT DAMPER

摘要

The present invention relates to a hydraulic damper for controlling the flow rate of a control damper, such as an electromotive power plant equipped with a feedback cam capable of controlling and operating a cylinder in a Rotorer characteristic curve with excellent control response speed and finely controllable Rotor characteristic curves.;In the present invention, an operation cylinder 25 having a crankshaft 22 connected to the piston rod end and a feedback cam 23 mounted at the center of the crankshaft, and an orifice hole 10a for supplying hydraulic pressure to both ends of the cylinder. And a chamber provided with an injection tube 11 for injecting hydraulic pressure into the orifice, and a movable coil 13 installed to rotate the lever 12 for pressing the injection tube 11. In the oil pressure regulator for adjusting the flow rate of the damper for ventilation equipment, the damper opening degree is moved from the middle part to the upper part which is the site | part which contacts the said feedback cam 23 with the 1st member 18a of the feedback lever 18. In order to control to be proportional to the square of the current supplied to 13), each round is formed with a different elliptical contact surface 23b so as to have a characteristic of a rooter curve, and having a feedback cam with excellent controllability.Providing hydraulic equipment for adjusting the flow rate of the buffer.
