た供給通路、出力通路及びドレン通路を備えた弁
本体、滑動孔に滑動自在に嵌挿されたスプール、
スプールを滑動孔内で軸線方向変位させる作動手
段及び供給通路に通じるオリフイスへ一定圧の油
圧を供給する圧油供給手段から構成され、スプー
ルには、供給通路と出力通路とを常に連通する環
状溝部とその環状溝部とドレン通路との連通関係

圧力制御スプール弁。 A valve body formed with a sliding hole and having at least a supply passage, an output passage, and a drain passage opened in the sliding hole; a spool slidably inserted into the sliding hole;
It consists of an actuation means for displacing the spool in the axial direction within the sliding hole, and a pressure oil supply means for supplying a constant pressure of oil pressure to an orifice communicating with the supply passage, and the spool has an annular groove that constantly communicates the supply passage and the output passage. A pressure control spool valve is formed with a land portion having a narrow land width that provides communication between the annular groove portion and the drain passage.
