Publication number: 20110175005Abstract: The structures of oil paths and switching control of a mechanical selector valve for controlling a hydraulic actuator and the cost of parts of the mechanical selector valve are respectively simplified and reduced to levels not achievable by an electromagnetic selector valve. However, simple and quick switching operation of the mechanical selector valve by the use of a nearby switch which requires small force to actuate is difficult, and this makes the mechanical selector valve less easy to operate than the electromagnetic selector valve. A selector valve operating mechanism (110) is provided with operating pistons (176, 179) which are hydraulic pistons connected through an operation link (161) to a spool (145) of a PTO selector valve (240), an solenoid valve (113) for hydraulically controlling reciprocation of the operating pistons (176, 179), and a controller (123) which is a control device for transmitting an operation signal to the solenoid valve (113).Type: ApplicationFiled: August 5, 2009Publication date: July 21, 2011Inventors: Kunihiko Sakamoto, Nagahiro Ogata, Masaaki Yamashita

Patent number: 7954315Abstract: A hydraulic circuit structure of a work vehicle capable of solving a problem in a conventional structure wherein, in a machine attitude control in back hoe operation, pressure oil is preferentially fed to light-loaded machines and some work machines are slowly moved or stopped and, accordingly, the attitudes of the machines cannot be rapidly controlled and work performance is affected. To solve this problem, the hydraulic circuit of the work vehicle comprises two valve groups for a loader and a back hoe having circuits to supply the pressure oil from one hydraulic pump to a valve group for back hoe control through a valve group for loader control and the pressure oil from the other hydraulic pump directly to the valve group for back hoe control. The pressure oil is independently supplied from the hydraulic pumps to valve sections for controlling right and left stabilizer cylinders installed in the valve group for back hoe control.Type: GrantFiled: January 23, 2006Date of Patent: June 7, 2011Assignee: Yanmar Co., Ltd.Inventor: Masaaki Yamashita
