  • Patent number: 7618045
    Abstract: The invention pertains to a sealing arrangement 10, 10a, which acts between a housing 12 and a component 14 installed in the housing 12, with a stop 16, permanently connected to the housing 12; with a spring 20, which is supported on the stop 16; and, with at least one first sealing element 22 in working connection with the spring 20. Abutment 34 is designed to be adjusted against the force of the spring such that the spring 20 is completely compressed—squeezed into a block—and additional load can be exerted on the sealing element 22, so that in particular any leakage which has developed can be stopped—on an emergency basis—by the exertion of additional load on the sealing element 22, which has the effect of increasing the sealing force which the sealing element 22 exerts.
