  • Hydraulic controller for transmission
    Patent number: 6655232
    Abstract: A hydraulic controller comprises a first hydraulic control valve 60, which is mounted on an end face S1 of a first housing unit H1, an oil pump 50, which is mounted on the first hydraulic control valve 60, and an input shaft 1 of a transmission, which shaft is provided rotatably in a transmission housing. The oil pump 50 comprises an outer rotor 52 and an inner rotor 53 in a pump casing 51 and 54, which is mounted on the valve body of the first hydraulic control valve 60. The input shaft 1, which is inserted into the pump casing and fit into the inner rotor 53, rotates and drives the inner rotor. The oil pump 50 sucks oil from the bottom of the transmission housing and supplies it through the mounted part into the first hydraulic control valve 60.
