A chassis dynamometer includes a frame, a roll set for engaging the wheels of a motor vehicle and an eddy current brake/inertia simulating unit with a rotor having ferrous metal rotor wheel rotatably mounted on the frame and a plurality of stationary field coils. The rotor has a rotational mass within the range of 70 to 90% of the base or minimum inertia of the dynamometer. A force transducer and a speed encoder provide a measure of the force applied to the roll by the wheel and the speed of the roll, respectively. A controller, in response to the roll speed and force applied to the roll controls the current to the field coils in accordance with a selected simulated inertia and road load for the vehicle.

A chassis dynamometer includes a frame, a roll set for engaging the wheels of a motor vehicle and an eddy current brake/inertia simulating unit with a ferrous metal rotor wheel rotatably mounted on the frame and a plurality of stationary field coils. The rotor wheel is in the form of an open ended drum and has a rotational mass which is equal to the trim inertia of the dynamometer, i. e. , the base or minimum inertia that the dynamometer is designed to simulate less the roll set inertia. The rotor wheel inertia is preferably within the range of a 70 to 90% of the base or minimum inertia of the dynamometer. A force transducer and a speed encoder provided a measure of the force applied to the roll by the wheel and the speed of the roll, respectively. A controller, in response to the roll speed and force applied to the roll controls the current to the field coils in accordance with a selected simulated inertia and road load for the vehicle.

A chassis dynamometer for testing motor vehicles in place includes a frame, at least one roll for engaging the wheel(s) driven by the vehicle engine and an eddy current brake/inertia unit in which the brake rotor is attached to one end of the roll to form an integral structure rotatably supported on the frame at each end of the structure.

A hydraulic fluid control system regulates the delivery rate of feed water to a boiler. A hydraulic actuated diaphragm pump having a plurality of diaphragm working chambers which are interconnected with check valve controlled inlets and outlets pumps the feed water to the boiler. Fluid surges or pulsations are prevented by the use of projection members on the face of the diaphragms and by a variably controlled pressure regulator responsive to the feed water pressure. The delivery rate of hydraulic fluid to the diaphragms controls the actual pumping output. A bypass line including a pressure regulating valve with pilot control and a modulating control valve controls a bypass hydraulic fluid rate which directly corresponds to the pumping output rate.
