|---|
| 060470000 | Externally operated multiway valve or interconnected control elements control motive fluid for a limited stroke to-and-fro device | 6 |
| 20090000293 | Power Plant - A power plant produces power by using high pressure gas to push a piston. The power plant uses a supply device to provide the high pressure gas to a cylinder and controls an admission valve and an exhaust valve to admit and exhaust the high pressure gas for pushing the piston and rotating a crank member to produce power. | 01-01-2009 |
| 20100287925 | Hydro-Mechanical Transmission And Valve Assembly - A hydro-mechanical transmission for an agriculture vehicle, such as a tractor. The transmission includes an input shaft, a hydrostatic unit driven by the input shaft, a mechanical transmission driven by the hydrostatic unit and/or the input shaft, and a valve assembly having a pressure control valve assembly to control an output speed of the hydrostatic unit. A mechanical shift control valve assembly is coupled with the mechanical transmission to selectively engage one of the gear sets of the mechanical transmission and adjust the hydrostatic unit speed. | 11-18-2010 |
| 20120285159 | HYDRAULIC DRIVING APPARATUS FOR WORKING MACHINE - Provided is an apparatus provided in a working machine to lower a load, comprising a hydraulic pump, a hydraulic actuator, a manipulation device having a manipulation member, a meter-in flow control device, a meter-out flow control device, a back pressure valve, a regeneration fluid passage branched from the meter-out fluid passage at a position upstream of the back pressure valve and merged with the meter-in fluid passage, and a check valve. The meter-in flow control device controls a meter-in flow rate in a region of the meter-in fluid passage upstream of a merging point with the regeneration fluid passage. The meter-out flow control device controls a meter-out flow rate in a region of the meter-out fluid passage upstream of a branching point of the regeneration fluid passage so as to make the meter-out flow rate be greater than the meter-in flow rate. | 11-15-2012 |
| 20130247554 | Remotely Controlled Vehicle Pedal Actuator - The Remotely Controlled Vehicle Pedal Actuator is a pneumatically powered tool for use in the motor vehicle repair and maintenance industry that enables a mechanic to solely, remotely, and repetitively depress and retract a vehicle accelerator, clutch or brake pedal. The device comprises a pneumatic linear actuator (commonly termed an air cylinder) that is pneumatically connected to a foot, hand or electronically activated pneumatic valve and a pneumatic power source. One end of the actuator is attached to a vehicle steering wheel with the opposite end attached to the vehicle accelerator, clutch or brake pedal. Activating the pneumatic valve pressurizes the actuator causing the actuator rod arm to extend and depress the vehicle pedal. Deactivating the pneumatic valve depressurizes the actuator causing the actuator rod arm to withdraw and retract the vehicle pedal. | 09-26-2013 |
| 060471000 | Having plural distinct or separately operable output means | 2 |
| 20080209903 | Hydraulic Drive Device for Working Vehicle - [Object] To materialize a reduction in pump loss, the assurance of sufficient working device speeds and the priority assurance of an adequate steering capacity with simpler construction and at lower cost than a load sensing system. | 09-04-2008 |
| 20130298545 | HYDROSTATIC SYSTEM CONFIGURED TO BE INTEGRATED IN AN EXCAVATOR - A hydrostatic system is configured to be integrated in a vehicle, e.g. an excavator. The hydrostatic system may comprise a first closed hydraulic circuit including a first hydraulic pump and a first hydraulic motor configured to operate a first component of the vehicle, and a second closed hydraulic circuit including a second hydraulic pump and a second hydraulic motor rated to operate a second component of the vehicle. Furthermore, a single six-port two-position directional valve may be provided. The single six-port two-position directional valve may be configured to switch between a first position and a second position such that in the first position the first hydraulic motor is driven by the first hydraulic pump and the second hydraulic motor is driven by the second hydraulic pump, and in the second position the first hydraulic motor is disconnected from the first hydraulic pump and the second hydraulic motor is driven by both the first and second hydraulic pumps. The present disclosure also refers to a method for operating a hydrostatic system configured to be integrated in a vehicle. | 11-14-2013 |
