Embodiment Construction

[0033] figure 1 A prolate spheroidal container body 1 is shown having a cylindrical main part 10 and two generally dome-shaped ends, a lower end 11 and an upper end 12 . The round upper end 12 has the filling and dispensing head 2 . As shown, the filling and dispensing head 2 comprises in particular a connection interface 3 , an indicator 4 indicating the filling level, a drop-resistant shield 5 and a central opening 6 providing access to the interior of the container 1 .

[0034] refer to figure 2 , the container 1 comprises a hermetically sealed inner shell 13 (or "liner") made, for example, of aluminum alloy or the like, and used to hold a fluid, in particular a pressurized gas. The shell 13 is reinforced on its outer surface by the winding of carbon fiber filaments 14 bonded together with epoxy resin or any other equivalent.

[0035] A rectangular filling and dispensing head 2 is placed inside the container 1 , at the opening of the container 1 and inside the housing 1...

Abstract

The invention relates to a device for controlling the filling and / or extraction of a fluid, for example, in relation to a pressurised fluid tank including a body having a connection end (516) which isequipped with engagement means that are intended to co-operate with complementary engagement means which are provided, for example, on a connection interface of a tank, a member (17) for opening a valve that can move in relation to the body, actuation means (250) which can move the opening member (17) selectively and which can move between a running position and a stopped position corresponding respectively to an operating position and a rest position of the opening member (17) and a hole (105) which can receive a removable outlet or inlet coupling (75) for the distribution of the fluid. Theinvention is characterised in that the device includes retractable locking means (55) which are used to lock the actuation means (250) in the running position and which are designed to co-operate withthe hole (105), such that, when there is no coupling (75) connected to the control device in the corresponding hole, the locking means (55) are biased towards the retracted position, thereby preventing the actuation means (250) from being stably maintained in the running position.

Description

technical field [0001] The invention relates to a device for controlled filling and / or extraction of fluid and an assembly comprising a container and said device. [0002] The invention relates more particularly to a device for controlling the filling and / or extraction of fluid, in particular in pressurized fluid containers, said device comprising: a body having a connection end equipped with a device for connecting with, in particular An engagement member cooperating with a complementary engagement member on a connection interface of the container; a member for opening a valve movable relative to said body; an actuation member capable of selectively moving said opening member, said actuation a member movable between an open position and a closed position respectively corresponding to the operative and inoperative positions of said opening member; for receiving a detachable outlet coupling or inlet coupling for dispensing fluid from or to the container opening.
