| 20080206073 | Fluid-Working Machines - A fluid-working machine comprises at least one primary working chamber such as a cylinder ( | 08-28-2008 |
| 20080245322 | Valvetrain Control Arrangement - A valvetrain control arrangement for an internal combustion engine. A fluid-working machine ( | 10-09-2008 |
| 20090235657 | COOLING SYSTEM AND A TRANSMISSION SYSTEM HAVING SAID COOLING SYSTEM INTEGRATED THEREWITH - The present invention provides a cooling system such as employed in cooling a heat source and a transmission system having said cooling system integrated therewith. The cooling system further includes a pump for supplying hydraulic fluid under pressure to a motor for driving a fan employed in the cooling process. In operation, a controller initiates operation of the pump such as to supply hydraulic fluid to said motor only when needed, thereby to improve the efficiency and controllability of the cooling system. | 09-24-2009 |
