Claims (1)
要素に選択的に導ひくことにより該ポンプの圧力対流量
特性を圧力の上昇に対して吐出量が減少する定馬力特性
に近づけるように制御する流体制御装置において、前記
ポンプの吐出圧油を負荷へ向けて流す通路内に配設され
たオリフィスと、該オリフィス入口圧力を大なる受圧面
積で一方の端面に受けると共に該オリフィス出口圧力を
調整可能なばねによるばね力と共に他方の端面に受けて
前記オリフィス前後に生じる差圧に応じて作動し前記ポ
ンプの吐出量制御要素に吐出圧を導びくコンペンセータ
弁とを備えてなることを特徴とする流体制御装置。By selectively guiding the discharge pressure of a variable displacement hydraulic pump to a discharge rate control element of the pump, the pressure versus flow rate characteristics of the pump can be brought close to constant horsepower characteristics in which the discharge rate decreases as pressure increases. A fluid control device for controlling a fluid includes an orifice disposed in a passage through which pressure oil discharged from the pump flows toward a load, and one end face receiving the orifice inlet pressure with a large pressure receiving area and receiving the orifice outlet pressure. The pump is characterized by comprising a compensator valve which receives a spring force from an adjustable spring and a compensator valve which operates in response to the differential pressure generated before and after the orifice and guides the discharge pressure to the discharge amount control element of the pump. Fluid control device.
