Three variants of execution of a deposit-type capacity containing a case, including a sidewall, lower bottom and head, in which, at least, one hatch (4) with a cover (5) supplied with a seal element (9, 33) and a cover holding device (10, 35) in relation to an edge of the hatch, and a chamber (13) made of an elastic material and placed inside the case, the edge part of which is fixed, a cavity (12) being formed between the case and the chamber, is suggested. The capacity in all variants contains additionally a device (11) of air supply to the cavity and a device (11, 38) of the cavity hermetic sealing, which subject to a variant of execution can be executed either in the bottom of the capacity or in the hatch cover. In the second and third variants of execution, at least, one hole (6) with a neck (7, 25, 26) and a closing element (8) supplied with a seal element and a holding device, and in the third variant of execution also a device (18) of split holding of the chamber edge part are executed additionally in the hatch cover. In various variants the chamber edge part is hermetically fixed either on the hatch edge or on the neck of the hole, executed in the cover.Capacities of the described design can be made directly either during modernization process of the standard design capacities, in particular, through execution according to one of the variants of execution in the head of the hatch and neck cover, the designs of which are also suggested in the context of the present application. |
