Definitions
- the invention relates to a pneumatic cylinder according to the Preamble of claim 1.
- Such a pneumatic cylinder is from GB 2 001 703 A. known.
- Two pistons are provided are arranged coaxially to each other.
- the pistons are as Hollow piston formed and acted upon by compression springs.
- a similar pneumatic cylinder is from DE 22 32 709 C2 known. Here is a single piston inside of a cylinder movable. A compressive force from Cylinder via a lever system on a piston rod transfer.
- Pneumatic cylinders are one compared to hydraulic cylinders very economical, environmentally friendly and popular Machine element that is used in a wide variety of areas Technology is used.
- the limits of using Pneumatic cylinders are, however, where there are high forces are required, but only small installation spaces are available stand. For this reason, pneumatic cylinders are according to the hardly any of the two cited references for high forces useful.
- the invention has for its object a Pneumatic cylinder according to the preamble of claim 1 to be designed in such a way that it transfers great forces can, but only requires small dimensions.
- This Task is characterized by the characteristics of Claim 1 solved.
- the pneumatic cylinder shown has two pistons 1, 2. These are arranged coaxially to one another and in one Housing 3 movable.
- Piston 1 - the lower of the two Piston - has a piston rod on.
- This piston rod is fixed with piston 1 connected through a bore 5 in Bottom 3.1 of the housing 3 passed down, and through a corresponding hole passed upwards in the upper piston 2.
- the piston rod has an upper part 4.2 and a lower part 4.1.
- Annular chamber 7 formed between the piston 1 and the bottom 3.1 of the housing 3 is one Annular chamber 7 formed. This has an inlet 7.1 for Print media on.
- a further chamber 8 with an inlet 8.1 intended.
- the lid 3.2 of the housing 3 carries double levers 9.1 and 9.2. These can be tilted using bearing pins 10.1 and 10.2 stored.
- Piston 2 has pressure sliding shoes 11.1, 11.2.
- the Pressure shoes 11.1 and 11.2 stand with the outer ends the outer lever arms of levers 9.1 and 9.2 in Active connection.
- the ends of the inner lever arms of the two Levers 9.1 and 9.2 act on similar sliding shoes 12, and thus on the end face of the piston rod 4.2.
- Chamber 8 pressurized. Should a movement of Piston 1 and piston rod in the Opposite direction, chamber 7 acted upon.

Claims (1)
- Vérin pneumatique, en particulier vérin pneumatique à course courte et à puissance de piston élevée,avec un corps de cylindre présentant un alésage cylindrique pour le guidage du piston et de la tige de piston,avec deux pistons (1, 2) qui se déplacent dans des directions opposées dans le sens longitudinal afin de produire une surpression d'air entre eux,avec un système de leviers mécaniques et un couvercle de fermeture, dans lequel le premier (1) des deux pistons (1, 2) est relié à la tige de piston et le deuxième (2) des deux pistons (1, 2) est coaxial par rapport au premier piston (1),
le deuxième (2) des deux pistons (1, 2) est relié au système de leviers du côté de l'espace cylindrique opposé au premier (1) des deux pistons (1, 2);
la force de pression exercée par le deuxième piston (2) est transmise à la tige de piston par le système de leviers en sens inverse du sens de déplacement du deuxième piston (2).
