摘要： An oil pump includes a first spill passage formed on a side surface (60) of a pump chamber (58) to communicate a hydraulic pressure chamber (54) with a first high pressure discharge passage (68) when the entire hydraulic pressure chamber (54) is positioned between the first high pressure discharge passage (68) and a first low pressure discharge passage (70). Therefore, when the hydraulic pressure chamber (54) passes between the first high pressure discharge passage (68) and the first low pressure discharge passage (70), the hydraulic pressure inside the predetermined hydraulic pressure chamber (54) escapes to the first high pressure discharge passage (68) through a first spill passage (76), so a hydraulic pressure value inside the hydraulic pressure chamber (54) is maintained at the pressure value inside the first high pressure discharge passage (68). As a result, fluid is inhibited from flowing into the hydraulic pressure chamber (54) from the first high pressure discharge passage (68) through a space between inner peripheral teeth (48) and outer peripheral teeth (42).
摘要翻译：油泵包括形成在泵室（58）的侧表面（60）上的第一溢流通道，用于在整个液压室（54）处连通液压室（54）与第一高压排放通道（68））位于第一高压排出通道（68）和第一低压排出通道（70）之间。因此，当液压室54通过第一高压排出通路68和第一低压排出通路70之间时，预定的液压室54内的液压从第一高压通过第一溢流通道（76）排出通道（68），使得液压室（54）内的液压值保持在第一高压排出通道（68）内的压力值。结果，流体被阻止从第一高压排出通道（68）通过内周齿（48）和外周齿（42）之间的空间流入液压室（54）。

摘要： In a hydraulic control system for a transmission, line pressure Pl is adjusted in accordance with a second solenoid pressure Psls if the ratio of a first sheave pressure Pin with respect to a second solenoid pressure Psls is equal to or less than the gain α. If not so, the line pressure Pl is adjusted in accordance with the first sheave pressure Pin. Consequently, the gain η of the first sheave pressure Pin with respect to a first solenoid pressure Pslp at a first sheave pressure adjustment valve 16 and the gain α of a second sheave pressure Pout with respect to the second solenoid pressure Psls at a second sheave pressure adjustment valve 17 can be individually set while the line pressure Pl can be suppressed to the substantially requisite minimum in the entire control region.

摘要： In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (S OUT ) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.
