Abstract
A piston and cylinder device with a piston mounted for reciprocating movement in the cylinder has on the outside of the cylinder an elongated mounting element comprising two guiding members on each of which a limit switch is mounted for positioning longitudinally of the cylinder. The limit switch is formed with a switch blade of ferromagnetic material and the piston has an annular rim constituted of permanent magnetic material. The switches can be adjusted longitudinally for the purpose of adjusting the stroke of the piston.
Claims4
A piston and cylinder device comprising
- an elongated hollow enclosed cylinder having an exposed outer surface;
- a piston positioned within said cylinder and capable of reciprocating movement along the elongation direction thereof based on working medium input into said cylinder;
- an elongated mounting element positioned on the outer surface of said cylinder and extending parallel to the elongation direction thereof, said elongated mounting element including an elongated base and two elongated webs connected to said base and extending away therefrom in a V-shaped fashion along the elongation direction of said base;
- two limit switches mounted on said mounting element, each being respectively mounted on one of said elongated webs so as to be independently movable along the elongation direction of said mounting element and thus said cylinder, each of said two limit switches being activated by movements of said piston past their positions and capable of controlling the admission of working medium into said cylinder and thus the movement of said piston therewithin.
