摘要:
A pressure control valve includes a sleeve on which an input port, an output port, and drain ports are formed; and a linear solenoid portion for generating thrust. The pressure control valve further includes a first spool, which advances and retreats within the sleeve, for receiving the thrust, regulating input pressure input to the input port, and outputting the regulated output pressure from the output port; and a second spool, which advances and retreats within the sleeve, for receiving the thrust, and selectively applying output pressure to the first spool. The output pressure is selectively applied to the first spool, thereby doing away with the need for a control valve or the like. This simplifies the oil pressure circuit for generating control pressure, and allows control pressure to be generated in a stable manner, and the size of the pressure control valve to be reduced.
