切換弁。 In a flow path switching valve that communicates a single normal port with either a high pressure port or a low pressure port, a control chamber in which the normal port, high pressure port, and low pressure port are each opened; and an opening of the low pressure port to the control room. A valve seat formed at the end; A reed valve having one end fixed to the control chamber wall and having an elasticity such that its free end always comes into contact with the valve seat; A high pressure port formed adjacent to the control chamber communicating with the reed valve. a valve chamber; a check valve disposed within the valve chamber and movable in response to supply pressure supplied to the high-pressure port; a valve seat that the check valve comes into contact with to close the high-pressure port; the above-mentioned reed valve. and a control arm disposed within the control chamber that has an engaging portion with the check valve and opens and closes the check valve, and the control arm is in a position where the reed valve is opened and the check valve is closed; A flow path switching valve characterized in that its movement is controlled to a position where a reed valve is closed and a check valve is opened.
