| 摘要 |
<p>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 is equipped 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. The invention 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 with the 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.</p> |
