装置。 In a pilot valve device in which the end of the spool valve faces the pilot chamber and the pilot pressure from the pilot pump is guided to the pilot chamber via the pilot valve, a relief valve is installed in the passage connecting the pilot pump and the tank. and a pressure loss generating means, and a passage downstream of the relief valve and connected to the upstream side of the pressure loss generating means communicates with the pilot chamber of the spool valve, and only the flow from this passage to the pilot chamber is provided. A pilot valve device equipped with a check valve that allows
