Abstract: A hydraulic energy conversion device includes a main body being an annular member having a central hole, an output shaft mounted in the central hole of the main body with a centerline extended perpendicular to the central hole; a fixing plate located at an end of the main body and provided with a plurality of passage holes; an outer cover located at another end of the main body opposite to the fixing plate and having a central opening for the output shaft to outwardly extended through the outer cover; and a plurality of vanes circumferentially spaced on the output shaft to locate in a space defined between the main body, the fixing plate and the outer cover. The hydraulic energy conversion device is mounted in a hydraulic shock absorber to convert hydraulic energy into mechanical energy and output the same without hindering the hydraulic shock absorber from normal operation.

Abstract: A hydraulic brake system includes a body with cavities, a vacuum brake booster port, a first caliber port and a channel system defined therein. An accumulator is located in a first one of the cavities. A first proportional solenoid valve is located in a second one of the cavities. A traction control valve is located in a third one of the cavities. The channel system is connected to the accumulator, the first proportional solenoid valve and the traction control valve via the first, second and third cavities. The channel system is further connected to the vacuum brake booster port and the first caliber port. The vacuum brake booster port, the accumulator, the first proportional solenoid valve, the traction control valve and the channel system are used together to control brake fluid to exert a first baking force on the first caliber port.

Abstract: The present invention relates to a vibration energy harvest device. In the present invention, the vibration energy harvest device is provided for being used to recycle the mechanical energy and thermal energy generated during the vibration, and effectively to improve the power generation efficiency with newly added hydraulic motor and electricity generating unit. Wherein by using an ameliorating valve module and removing the damping hole in the prior art, no matter the damping oil flows from inner cylinder module through hydraulic motor to outer cylinder module or the contrary direction, the flowing damping oil could avoid the hydraulic motor from reciprocating to improve the power generation efficiency.
