  • Road vehicle-actuated air compressor and system therefor
    Patent number: 4173431
    Abstract: A road vehicle-actuated air compressor and a system are disclosed for utilizing compressed air to operate an electrical generator to generate electricity. The road vehicle-actuated air compressor includes an actuator, a cylinder, and a piston in the cylinder reciprocatable in response to actuation of the actuator by a vehicle for compressing air in the cylinder. The cylinder is provided with a first vent means for introducing air into the cylinder behind the piston during a forward stroke of the piston, a valve-controlled second vent means for introducing air into the cylinder on the other side of the piston during the reverse stroke thereof, and outlet means for supplying air compressed by the piston during the forward stroke thereof to a utilization device.
    Type: Grant

  • Water vehicle-actuated air compressor and system therefor
    Patent number: 4160624
    Abstract: A water vehicle-actuated air compressor and a system are disclosed for utilizing compressed air to operate an electrical generator to generate electricity. The water vehicle-actuated air compressor includes an actuator, a cylinder, and a piston in the cylinder reciprocable in response to actuation of the actuator by the motion of the vehicle through the water for compressing air in the cylinder. The cylinder is provided with a first vent means for introducing air into the cylinder behind the piston during a forward stroke of the piston, a valve-controlled second vent means for introducing air into the cylinder on the other side of the piston during the reverse stroke thereof, and outlet means for supplying air compressed by the piston during the forward stroke thereof to a utilization device.
