20110099994 | POSITIVELY ENGAGING SHIFTING ELEMENT WHICH CAN BE HYDRAULICALLY OR PNEUMATICALLY ACTUATED - The invention relates to a positively engaging shifting element which can be hydraulically or pneumatically actuated, comprising a hydraulically or pneumatically actuatable piston (I) having a piston compartment ( | 05-05-2011 |
20110173966 | HYDRAULIC AGREGATE - The invention relates to a hydraulic aggregate, particularly for supplying conveyor and lifting devices with pressurized fluid, having a tank ( | 07-21-2011 |
20130283777 | HYDRAULIC CONTROL SYSTEM HAVING ENERGY RECOVERY - A hydraulic control system is disclosed for use with a machine. The hydraulic control system may have a pump, a tank, and an actuator. The hydraulic control system may also have at least a first valve configured to control fluid flow between the pump, the tank, a first chamber of the actuator, and a second chamber of the actuator; a second valve fluidly disposed between the second chamber and the tank; and a third valve fluidly disposed between the first and second chambers. The hydraulic control system may further have a controller configured to selectively cause the second valve to block fluid flow from the second chamber of the actuator to the tank, and to selectively cause the third valve to fluidly communicate the first and second chambers of the actuator when the second valve blocks fluid flow from the second chamber of the actuator to the tank. | 10-31-2013 |
20140325976 | BOOM CONSTRUCTION FOR A TRUCK-MOUNTED CONCRETE PUMP - A boom construction for truck-mounted concrete pumps has at least a first boom arm and a second boom arm that are articulatedly jointed to each other and that are rotatable relatively to each other about an axis. A drive pivots the boom arms. A piston-cylinder arrangement and a gear transform piston reciprocating movement into rotary movement for boom arm pivoting, said arrangement having first and second pistons that form part of the gear and that interact with outer rings of the gear. | 11-06-2014 |
20140366522 | ELECTRO HYDROSTATIC ACTUATOR - An electro hydrostatic actuator includes a single-rod cylinder having fixed and movable ends, a hydraulic supply source, and a reservoir provided in a hydraulic circuit and capable of storing operation oil. At a predetermined position of the single-rod cylinder close to the fixed end, the hydraulic supply source is disposed at the periphery of the single-rod cylinder, and is integrated with the single-rod cylinder. The reservoir is formed in a double cylindrical shape, and is, at a position close to the movable end relative to the hydraulic supply source, integrated with the single-rod cylinder in the state in which the single-rod cylinder is inserted into the reservoir so as to be coaxial with the reservoir. | 12-18-2014 |
