Abstract
A breathing valve with a valve disk lying on a valve crater and with a valve spring, which is in contact with the valve disk. A first spring end is provided in contact with a support surface and a second spring end is provided. The valve disk is accommodated in a guide displaceable along an axial valve axis, and the valve spring is fastened such that the line of action of the spring is directed at an angle in relation to the valve axis. The valve is extensively prevented from vibrating.
