Abstract
Abstract An energy-accumulating system for use in a motor vehicle is disclosed which includes a flywheel which rotates to store energy, a first hydraulic pump motor for rotating with the flywheel, ground engaging wheels driven by a second hydraulic pump motor, and computing valves interconnecting speed sensors and operator controls for controlling fluid flowing between the first and second pump motors. Details of the computing valves are also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
An energy-accumulating system for use in a vehicle; said system including: a flywheel (38) for rotating stored energy; a first hydraulic pump/motor (2) for rotating with said flywheel (38); a ground engaging wheel (8); a second hydraulic pump/motor (5) for rotating with said wheel; control means (30) responsive to signals applied thereto for selectively controlling the flow of fluid between said first and second hydraulic pump/motors so that the energy stored in said flywheel (38) can be controlled in relationship to an operator control and the speed of rotation of said ground engaging wheel (8).
Claim 2
Dependent Claim
95 words
An energy-accumulating system for use in a vehicle; said system including: a flywheel (38) for rotating stored energy; a first hydraulic pump/motor (2) for rotating with said flywheel (38); a ground engaging wheel (8); a second hydraulic pump/motor (5) for rotating with said wheel; control means (30) responsive to signals applied thereto for selectively controlling the flow of fluid between said first and second hydraulic pump/motors so that the energy stored in said flywheel (38) can be controlled in relationship to an operator control and the speed of rotation of said ground engaging wheel (8).
Claim 3
Dependent Claim
49 words
The system as defined in claim 1, also including: an operator control device (25) for providing a first signal to said control means (30); and means (43) responsive to the speed of rotation of said ground engaging wheel (8) for providing a second signal to said control means (30).
Claim 4
Dependent Claim
44 words
The system as defined in claim 2, also including: a second operator control device (26) for providing a third signal to said control means (30); said first operator control device (25) being an accelerator and said second operator control device (26) being a brake.
Claim 5
Dependent Claim
18 words
The system as defined in claim 3 in which said control means is a computing hydraulic valve (30).
