In a buffer pressure control mechanism for an automatic transmission in which piping is branched to a valve, a shield that causes turbulence in the flow of pressure oil is installed near the inlet or outlet of the solenoid valve. Features a pressure control mechanism. 2. A shield installed near the inlet of the solenoid valve is molded from a shape memory alloy, and the shield has shape memory for setting a space for inserting a jig at room temperature. The first characterized by
Pressure control mechanism as described in section. 3. It has a supply pressure section piped from the pressure source to the orifice, and a control pressure section piped from the orifice to the solenoid valve, with piping branched from the upstream side of the solenoid valve of the control pressure section to the control valve. A pressure control mechanism for buffering an automatic transmission, characterized in that the axis of the orifice and the axis of the solenoid valve are offset from each other to such an extent that turbulence occurs in the flow of pressure oil. 4. It has a supply pressure section piped from the pressure source to the orifice, and a control pressure section piped from the orifice to the solenoid valve, with piping branched from the upstream side of the solenoid valve of the control pressure section to the control valve. 1. A pressure control mechanism for buffering an automatic transmission, characterized in that a piping flow path between the orifice and the solenoid valve is bent to the extent that turbulence occurs in the flow of pressure oil.
