The pressure-stabilizing, liquid-supplementing and gas-exhausting device of the closed liquid cooling system is low in cost and convenient in operation. The pressure-stabilizing, liquid-supplementing and gas-exhausting device of the closed liquid cooling system is of a great practical value.

The present invention provides a laminated exterior body for electrochemical elements capable of attaching a porous metal sheet as a safety valve with sufficient strength. The present invention is aimed at a laminated type electrochemical element exterior body, in which two exterior films (11) whose sealant layer on one side is made of a polymer compound are laminated in a state where both sealant layers face each other, and The outer periphery of the laminated exterior film (11) is sealed. One end side of the safety valve (2) for preventing internal pressure rise made of porous metal sheet (21) is arranged inside, and the other end side is arranged outside, and the safety valve (2) is sandwiched between two laminated sheets In the state between the corresponding outer edges of the exterior film (11), the safety valve (2) is fixed to the sealant layer of the exterior film (11) via the adhesive layer (3) containing a polymer compound.

A venting device for a hydraulic control unit, designed as a diaphragm in a bore in the control unit, so that collected air can escape, via the diaphragm, to outside the housing. A membrane, which is permeable to air and oil when under pressure, closes the diaphragm bore with respect to the outside. The housing bore and the diaphragm form an inside space that can be vented, via the membrane. The inside space being delimited, during operation, by the diaphragm and an oil column which passes from the control unit into the housing bore and is continually maintained at a defined pressure at which oil, in the housing bore, either does not pass through the membrane or only a minute amount passes therethrough. The oil column remains in the housing bore so that only air, contained in the oil, is vented to the outside without any air being drawn into the control unit from outside.

The invention relates to a fiber impregnation system. The fiber impregnation system comprises a fiber impregnation box (110) and a driving pump (120) connected with the fiber impregnation box (110) by one or more refluxing hoses (122), wherein the refluxing hoses (122-1, 122-2 and 122-3) are used for recycling resin from the fiber impregnation box and refilling the fiber impregnation box with the resin under the driving action of the driving pump; and preferentially, the driving pump (120) is a peristaltic pump or a diaphragm pump. Besides, the invention also relates to equipment for performing pultrusion on fibers (100) to obtain a section material (200) by use of the fiber impregnation box. According to the fiber impregnation system, the fiber impregnation box and the peristaltic pump provided with at least one pump head are combined, and the quantity of pumps, pump heads and pipelines is increased as required by production and processing, thus, the fiber impregnation box is not required to be closely connected with a corresponding molding and solidifying device, and a yarn guiding plate can be arranged in the fiber impregnation box; and the fiber impregnation box and the corresponding molding and solidifying device can be separable and vacuumizing operation is carried out, and thus, the fiber exhaust efficiency is improved.
