ELECTOMOTIVE THREE-WAY VALVE

摘要

PURPOSE: An electric three-way valve is provided to maintain a valve core in parallel and to slide a valve seat in a rotary direction of the valve core. CONSTITUTION: An electric three-way valve(10) comprises an input, a plurality of outlets, and a valve core(23). The valve core is slid in a valve seat(11a) by a driving force of a motor unit and selectively opens and closes the outlets. The motor unit is mounted on the outside of the upper end surface of a cylindrical casing(11) which introduces a refrigerant. The valve seat is installed at a lower opening unit of the cylindrical casing. The valve core delivers the driving force of the motor unit and is driven by a gear device arranged inside the cylindrical casing. The cylindrical casing comprises a sidewall with the opening unit of the cylindrical casing and a top unit and the valve seat is installed in the opening unit.
