The balance of pressure to compensate for variations in the volume of a medium device, electrical connection for use in underwater or in a humid environment or harsh, set of pressure compensation and method of manufacture of a pressure balance

摘要

The present invention relates to a pressure balance to compensate for variations in the volume of a medium. The pressure balance has a first part of the balance (10) and a second part of the balance (20). The first part of the balance (10) contains a first volume (12) and the second part of the balance (20) contains a second volume (22).The first and second volumes (12, 22) are in flow communication. The first part of the balance (10) includes a first portion of the bellows (11), and the second part of the balance (20) includes a second portion of the bellows (21).A moving element (30) is provided, to which the first portion of the bellows (11) and the second portion of the bellows (21) are mechanically coupled together such that the displacement of the movable element (30) along a predetermined axis resulting in the compression of one of the portions of the bellows (11, 21) and In the expansion of another portion of the bellows (11, 21).
