摘要： An oil pump includes a pump cover covering a recess in a side face of a pump body to form a gear compartment therebetween. A drive gear and a rotatably driven gear are meshed and mounted in the gear compartment. Working spaces R are formed by the engagement of the meshed gear teeth. Discharge ports are formed in both the pump body and the pump cover in communication with the gear compartment. A notch is formed in the pump body at the bottom of the gear compartment and extends from the front end of the discharge port in the pump body to the rear end of a discharge area for the working spaces. Another notch is formed in the inner side face of the pump cover, and extends from the front end of the discharge port in the cover to the rear end of the discharge area.

摘要： A speed change control system for an automatic transmission, for selectively switching a plurality of speed change control modes of different speed change control contents to control a gear ratio of an automatic transmission disposed on an output side of a prime mover. A first speed change control mode is selected if an output demand for the prime mover is in a predetermined state, and the first speed change control mode is switched to a second speed change control mode, if a physical quantity relating to a speed of the prime mover is in a predetermined state when the first speed change control mode is selected.
