リリーフ弁の設定圧力[Scope of Claim for Utility Model Registration] A static electricity system in which the rotation of a drive cam drives a cylinder whose output pressure is regulated by a relief valve, and the pressure oil generated in the cylinder is sent to a hydraulic actuator with a pressure accumulator. In the hydraulic circuit, the pressurization amount ΔX 1 and the pressure reduction amount ΔX 2 at the stroke end of the drive cam are set based on the following equations (1) and (2),
A drive cam in a hydrostatic circuit, characterized in that an operation pattern is generated after the pressurization and depressurization are completely completed. Δx 2 = VBA 0 (Ps 1 - 1 )...(1) Δx 1 = VBA 0 ( 1 - P 2 )...(2) Here, B: Bulk modulus of hydraulic oil in the pipe V: Operation in the pipe Oil volume A 0 : Cylinder pressure receiving area 1 = (A 2 /A 1 )P 2 , Ps 1 :
