摘要：
A pressure variable valve apparatus includes a mover constituted to be embedded in the body and movable linearly in B direction in a main body to change pressure for releasing closure of a valve flow path by a valve element, a fixed magnetic marker provided unmovably to the main body and a variable magnetic marker integrally formed with the mover. Meanwhile, a set pressure detecting apparatus includes a magnetic sensor and a supporter for supporting from outside of the body the magnetic sensor scannably in direction for moving the variable magnetic marker to provide detected output in accordance with positions of the fixed magnetic marker and the movable magnetic marker of the valve apparatus from the magnetic sensor.
