Abstract
The invention concerns a ventilation opening 1 for a gear box 2. The volume of air enclosed in a gear box 2 varies as a result of variations in temperature. An increase in temperature causes an increase in pressure, whereas during a reduction of temperature in the gear box 2 a reduction of pressure occurs. When the oil present in gear box 2 is placed in turbulence, an oil foam is formed. The ventilation of opening 1 permits compensation of the pressure and prevents escape of oil as well as entry of dirt, etc. The ventilation opening 1 has an expansion chamber 9, which according to the invention is designed as a flexible container 10. The external dimensions of container 10 are greater than opening 3 of the gear box 2, in which opening the ventilation opening 1 is screwed. Since the container 10 must be flexible, on the one hand, but must also be sufficiently rigid, on the other, it is advantageous to design the container 10 from an elastomer. <IMAGE>
