  • Patent number: 8636483
    Abstract: A pump apparatus configured with a first pump for pumping working fluid in accordance with a reciprocation of a piston using a space between a first open/close valve for suction and a second open/close valve for discharge as a pump chamber. The pump apparatus is also configured a first flow passage for supplying the working fluid from a supply source to an operation subject via the first open/close valve, the pump chamber, and the second open/close valve in accordance with an operation of the first pump. A second flow passage supplies the working fluid pumped by a second pump, which is different from the first pump, to the pump chamber. A selector is configured to select either the first flow passage or the second flow passage.

  • Patent number: 8539850
    Abstract: A manual valve is formed with a drain input port that closes if a shift is made to the D position, and opens for draining if a shift is made to the N position. A switching valve communicates an output port of a pressure regulating valve portion and an oil passage of a clutch and closes a drain port during engine operation when a line pressure is applied, and cuts off communication between the output port of the pressure regulating valve portion and the oil passage of the clutch and communicates the oil passage with the drain port during an engine automatic stop when the line pressure is not applied. The drain input port and the drain port are connected by a drain oil passage.
