Claims

[Claims for Utility Model Registration] A main body having a sliding hole to which a pressure fluid circuit and a discharge circuit are connected, and an inner hole connecting to the pressure fluid circuit via a main valve throttle, and the inside of the sliding hole of the main body. a main valve that is slidably fitted into the
A pressure control valve comprising a pressure chamber connected to an inner hole of the main valve and formed behind the main valve, and a pilot valve that opens and closes between this pressure chamber and a discharge circuit, the pressure chamber A poppet valve part has a valve chamber in the sliding hole of the main valve body, and the poppet valve part contacts the valve seat to form a gap between the valve seat and the sliding hole of the main valve body, and the poppet valve part slides into the inner hole of the main valve via a sealing member. A small diameter portion that is freely fitted, a large diameter portion that is slidably fitted into a sliding hole of the main body provided between the poppet valve portion and the small diameter portion, and the inner hole of the main valve communicates with the pressure chamber. A valve body having a passage is provided to form a valve chamber connected to the discharge circuit between the main valve and the large diameter part, and when the poppet valve part of the valve body abuts the valve seat, the main valve and the valve body A pressure control valve that is provided with a connecting mechanism between the small diameter portion of the valve body and the main valve to integrally connect the main valve and the valve body when the poppet valve part is separated from the valve seat.
