変速機の油圧回路。[Scope of Claim for Utility Model Registration] A friction element that is supplied with hydraulic pressure and connected to form a power transmission path, an accumulator valve that communicates with this friction element, and an oil pump that receives hydraulic pressure from an oil pump in the traveling position in response to driving operations. In a hydraulic circuit for an automatic transmission, the hydraulic circuit for an automatic transmission includes a manual valve that supplies the friction element to the friction element, and an orifice that is located between the clutch, the accumulator valve, and the manual valve. The hydraulic circuit of an automatic transmission consists of a spring that expands and contracts depending on the oil temperature, which urges the piston.
