Abstract
Abstract An apparatus for resiliently mounting a vibrating body, has a mounting bracket and a pedestal interconnected through a resilient element to define a liquid-filled hollow space. A compensating baffle bounds at least 10% of the liquid-filled hollow space and is moved by a positioning element to compensate for pressure variations in the liquid caused by vibrations, of the body. The positioning element is actuated by a primary element which detects the vibrations of the body, through a freely programmable control unit.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
An apparatus for the resilient mounting of a vibrating body, said apparatus comprising a mounting bracket and a pedestal which are interconnected through a resilient element that contains a liquid-filled hollow space, a compensating baffle associated with a positioning element being provided whose adjustment permits compensation of the pressure variations in the liquid caused by disturbing vibrations, characterized in that the compensating baffle (10) bounds the working space (9) itself and covers at least 10 percent of the boundary surface of the working space; that the positioning element (11) is adapted to be actuated by a primary element (12) which detects disturbing vibrations of said body; and that the primary element and the positioning element are interconnected through a freely programmable control unit (14).
Claim 2
Independent Claim
124 words
An apparatus for the resilient mounting of a vibrating body, said apparatus comprising a mounting bracket and a pedestal which are interconnected through a resilient element that contains a liquid-filled hollow space, a compensating baffle associated with a positioning element being provided whose adjustment permits compensation of the pressure variations in the liquid caused by disturbing vibrations, characterized in that the compensating baffle (10) bounds the working space (9) itself and covers at least 10 percent of the boundary surface of the working space; that the positioning element (11) is adapted to be actuated by a primary element (12) which detects disturbing vibrations of said body; and that the primary element and the positioning element are interconnected through a freely programmable control unit (14).
Claim 3
Dependent Claim
