Abstract: A variable displacement pump includes: a pump section arranged to be driven by an internal combustion engine, and to discharge a lubricant introduced from an induction portion to a plurality of hydraulic chambers, through a discharge portion, by volume variations of the hydraulic chambers; a variable mechanism arranged to move a movable member by using the discharge pressure of the lubricant, and to vary volumes of the hydraulic chambers which are opened to the discharge portion; and an urging section arranged to urge the movable member in a direction to increase quantities of the volume variations of the hydraulic chambers, the urging section having a spring constant which increases as a movement distance of the movable member in a direction to decrease the quantities of the volume variations of the hydraulic chambers increases.

Abstract translation: 可变排量泵包括：泵部分，其布置成由内燃机驱动，并且通过液压室的体积变化通过排出部分将从诱导部分引入的润滑剂排出到多个液压室; 可变机构，其被布置成通过使用润滑剂的排出压力移动可动构件，并且改变对排出​​部分敞开的液压室的容积; 以及推动部，其被设置成沿着增加液压室的体积变化量的方向推动可动件，所述推动部具有弹簧常数，该弹簧常数随着可移动部件在减小数量的方向的移动距离而增加 液压室的体积变化增大。
