摘要： The invention provides an electrically operated valve which can more accurately detect a position of a valve body. An electrically operated valve is provided with a valve shaft, a valve body, a rotor member which is movable together with the valve shaft in a parallel direction to a first direction, a stator member which applies a turning force to the rotor member, a permanent magnet member which turns together with the rotor member, an angle sensor which detects an angle of rotation of the permanent magnet, and a guide member which guides a relative movement of the rotor member or the valve shaft in relation to the permanent magnet member. A distance between the permanent magnet and the angle sensor is fixed when the permanent magnet member turns.

摘要： The invention provides an electrically operated valve which can control a flow rate precisely at a small flow rate distributing time and can circulate a fluid so as to prevent a pressure loss as much as possible at a large flow rate distributing time without an increase of a working and assembling cost. A movable valve seat body forming a main valve port for forming a small flow rate flow path extending from a first inlet and outlet to a second inlet and outlet is arranged between a valve chamber and a lower chamber. The movable valve seat body is structured such that its lower portion is slidably fitted and inserted to the lower chamber, and such as to serve as a float type check valve body for opening and blocking a large flow rate flow path extending from the second inlet and outlet to the first inlet and outlet.
