The invention concerns a method of preparing the respiratory air for an oxygen-air mixture wherein extremely pure oxygen gas is added to the air being inhaled. The volumetric amount of oxygen added to the oxygen-air mixture to be prepared depends on the given physical performance to be measured.
摘要:
A traction mechanism drive, in particular for an internal combustion engine, including a vibration damper (1) having a base part (2) and a rotary part (3) that can be rotated to a limited extent relative to the base part against the effect of an energy store (6). Between the base part (2) and the rotary part (3), a friction unit (8) having a friction ring (9) formed of a support element (15) and a sliding element (16) arranged radially outside of the support element (15) for forming a friction contact in relation to a friction surface (10) is effective. The friction ring (9) is produced in one piece from the support element (15) and the sliding element (16), and the support element (15) and the sliding element (16) are cast on top of each other. A positive fit (17) is effective between said support element and sliding element in the circumferential direction.
