Abstract: The wheel hop generator mechanism includes a plurality of forced oil feeders, assembled between the axles and vehicle body. The forced oil feeders includes a cylinder and a telescopic cylinder block, and oil inlet check valves and oil outlet check valves are placed at the motion position of the piston of the cylinder corresponding to the telescopic cylinder block. An oil tank, used to accommodate the oil required for actuation of the forced oil feeders is linked by an oil pipeline to the oil inlet check valve and oil outlet check valve, forming a common oil circulation loop. An oil drive motor is assembled at a predefined section on the oil pipeline and has an oil inlet portion, oil discharge portion and power output axle. The power output axle is mated with a generator. Vehicles can be powered continuously to ensure better power generation effect.

Abstract: The present invention provides an adjustable hydraulic damper for vehicles, which enables the running vehicle to generate kinetic energy through the extrusion of piston and piston rod in the hydraulic damper, thus allowing for circulating supply of high-pressure oil and providing kinetic energy to the vehicles under the control of inlet and outlet check valves installed on both sides of the hydraulic damper.

Abstract: A flush tank includes a water entrance to receive water from a water reservoir, a water outlet for discharging the water and controlled by a valve member, and a water inlet disposed in the upper portion to receive waste water from waste water suppliers. A valve device is attached to the lower portion of the tank member, to control and to allow little water to flow into the tank member via the water entrance. Another valve device is attached to the upper portion of the tank member, to control and to allow the waste water to flow into and to fill the tank member via the water inlet.
