Definitions
- the invention relates to a device for the Conveying a liquid or gaseous medium or for drive through a medium according to the generic term of claim 1.
- Such devices are for example as Compressors known.
- the well-known compressor has a piston / cylinder unit on which the piston by means of a piston rod and a crank mechanism is moved up and down.
- a valve assembly which consists of two check valves, which assigned to the cylinder unit ensures that ambient air as the piston moves down is sucked into the cylinder space and that with the subsequent upward movement of the piston the sucked-in air is expelled as conveying air becomes.
- a drive unit for example, an electric motor.
- An internal combustion engine emerges from FR 15 56 723 that oscillates in a combustion chamber Displaceable piston, the piston by means of an arranged outside the combustion chamber Camp is guided.
- the first border on the combustion chamber and second cylinder walls, each one Face of the piston are facing, wherein in the cylinder walls each have at least one check valve is arranged.
- Via the check valves the exhaust gases are removed from the combustion chamber.
- the fuel intake into the combustion chamber takes place via openings that are in the combustion chamber side sealing side walls are located. Because of this valve arrangement, the internal combustion engine needs a relatively large amount of space. moreover is an arrangement of several valves with large valve areas due to the small cylinder wall area not possible, so the flow losses are high.
- the invention has for its object a device of the type mentioned at the beginning, which does not have these disadvantages.
- a device with the features of claim 1 proposed.
- This is characterized in that the piston of at least a check valve is interspersed. Thereby, that each of the two cylinder walls each is penetrated by a check valve a first by a corresponding piston movement Check valve opened and the medium in the cylinder chamber be sucked in. Then follows the piston moves back so that the medium conveyed flows through the piston and then - at one another piston stroke - through a second check valve emerges in the other cylinder wall. Since the Flow direction of the medium in the cylinder space, in the piston is moving, not be reversed must, this has an advantageous effect with resonance charging on. Furthermore, is in each of the cylinder walls only one valve required, so big Valve surfaces can be realized, causing flow losses be reduced.
- the bearing to guide the movement of the piston is outside the cylinder. Due to this construction, it is possible to optimally guide the piston in the bearing so that he has a precisely defined and exact trajectory passes through and an extremely small distance adheres to the inner wall of the cylinder. On a Lubrication of the piston in the cylinder can therefore be dispensed with become. On additional sealants, such as for example discs made of metal, such as they are often used in known conveyors be in the gap between the pistons and the inner wall of the cylinder can be dispensed with.
- the bearing is a lubricant, for example Contains bearing grease or the like because it is arranged outside the cylinder and consequently no residues of the lubricant or the like in the cylinder and thus in the medium can reach.
