| 7258242 | Mobile crane boom having an autarchic hydraulic power unit mounted thereon The present invention relates to a mobile crane boom having a self-sufficient energy supply arranged on it for supplying hydraulic energy to at least one hydraulic load arranged on the mobile crane boom. The supply of the hydraulic load arranged on the mobile crane ... | 08/21/2007 |
| 7140631 | Automatic kick stand for two-wheeled vehicle An automated side stand for a two wheeled vehicle. A side stand assembly comprises a rotatable strut and an actuator attachable to the frame of a vehicle having two wheels. The actuator operates to rotate the strut between an up position and a down position. In the ... | 11/28/2006 |
| 6993905 | Oil hydraulic cylinder An oil hydraulic cylinder configured to allow an object to be smoothly and continuously lifted without being clatteringly swayed and unnecessarily rotated by the oil hydraulic while supply of the oil hydraulic remains uninterrupted when an adjusting lever is manipul... | 02/07/2006 |
| 6715282 | Actuator device, in particular for operating the stand of motorcycles, and automatically releasable hydraulic valve A valve and a device for actuating the rotation of a stand (4) of a motorcycle (2) comprising an hydraulic actuator (1) operating an actuating member (7) between a first and a second position bringing the stand (4) from a rest posi... | 04/06/2004 |
| 6679054 | Electro-hydraulic actuator of a motorcycle stand An actuating device (1) for the rotation of a stand (4) of a vehicle, such as a motorcycle or scooter, between a standing position and a rest position, and allowing also the reverse maneuver in order to rotate the stand from the position of vehicle on the... | 01/20/2004 |
| 6454033 | Electro-hydraulic vehicle with energy regeneration A vehicle including a battery (61) powering an electrical motor (60), the electric motor (60) operating when the vehicle is driving at a nominal speed in order to drive, at a constant speed, a variable displacement hydraulic pump (4) which is connected to... | 09/24/2002 |
| 5749224 | Extended range thruster system and method of determining thrust An electrohydraulic actuator has a housing divided into pump and cylinder portions respectively containing a centrifugal impeller driven through a hub by an externally mounted motor, and a pushrod actuated by a piston and arranged to advance the piston an... | 05/12/1998 |
| 5375418 | Controlled convertible top hydraulic lock A vehicle convertible top is moved by hydraulic cylinders between extreme raised and lowered positions.
