Abstract
A visual indicator of vacuum pressure in a pneumatic circuit includes a hollow body having a base and a top connected by a side wall having a window near the top; an element for coupling to the pneumatic circuit, the element being secured to the base and opening into the body via a pipe provided in the base; a bellows, which has a first, open end fastened to the base facing the pipe and a second, closed end, and which is deformable between an extended state, in which the second end extends near the top facing the window, and a retracted state, in which the second end extends between the base and the window; and a magnetic attraction device including a first element secured to a front wall of the second end of the bellows and a second element that is secured to the top.

Visual indicator of vacuum pressure in a pneumatic circuit, comprising:
- a hollow body having a base and a top which are connected by at least one side wall;
- an element for coupling to the pneumatic circuit, said element being secured to the base of the body and opening into the body via a pipe provided in the base of the body;
- a bellows, which has a first, open end fastened to the base facing the pipe and a second, closed end, and which is movable between an extended state, in which the second end is brought closer to the top, and a retracted state, in which the second end is brought closer to the base, the side wall having at least one window for viewing the bellows in one of its states;
- and
- a magnetic attraction device comprising a first element secured to a front wall of the second end of the bellows and a second element that is secured to the top in order to exert a predetermined retaining force on the first element when the bellows is in its extended state.
A gripping device having suction cups belonging to a pneumatic circuit to which at least one indicator according to any of the preceding claims is coupled.
