Ergometer e.g. bicycle ergometer for e.g. magnetocardiography instrument used in hospital, has flywheel which is actuated by operation of two-stage gear having preset transmission ratio

摘要

The ergometer (1) made of non-magnetic material, has a flywheel (15) which is actuated by the operation of two-stage gear (38) having preset transmission ratio. A pressurized gas or pressurized gas mixture operable brake unit (37) is provided for performing braking operation of the rotation of the flywheel. The braking force of the brake unit is adjustable by pressurized gas or pressurized gas mixture containing compressed air, nitrogen, oxygen, helium, or oxygen.
