Definitions
- the invention relates to a piston machine for conveying gases according to the Preamble of the 1st patent claim.
- Piston machines of the type presented here are used, among other things, in vacuum technology for the production of gases and for the production and maintenance of Pressure differences used as vacuum pumps.
- US 5,921,755 is one described such pump.
- the present invention relates to one or multi-stage construction methods.
- the pistons perform an oscillating movement between their two reversal points. When a piston moves upwards it becomes Gas compressed and expelled. A negative pressure is created during the downward movement in the displacement. Gases can flow into the displacement through suitable valves.
- the invention is based on the object of presenting a construction which additional unnecessary energy consumption and undesirable heating of the Pump components can be avoided. Special attention is paid to this control that in the area of the pump-active components (e.g. pistons and valves) none Dead spaces arise. These include gases during the pumping process thus significantly affect the pump properties.
- the pump-active components e.g. pistons and valves
- a cylindrical displacement 1 which is delimited by the piston cylinder wall 2
- the piston 3 performs an oscillating movement, which causes the promotion of gas is effected.
- the gas to be pumped passes through radial inlet openings 5 in the piston cylinder wall 2 in the area of the lower pressure point of the piston in the displacement 1 and is ejected via a valve 7 at the upper end of the displacement.
- the movement of the piston is controlled by a connecting rod 8 and a piston rod 10 is connected to a drive device.
- the axial limitation of the piston 3 is formed by the piston crown 12.
- the piston crown is according to the invention at the same time designed as a valve. For this purpose, it is provided with openings 14. This Openings are covered by a membrane, which depending on the embodiment as a plastic membrane 16, interspersed with ferromagnetic particles, or as magnetic plastic membrane 18 can be formed.
- the function of the valve includes a non-positive device, which is the membrane presses in the closed state to seal the openings 14.
- the non-positive device is inserted into a groove 20 Magnet ring 21 or magnetic segments 22 together with the plastic membrane 16 formed.
- the second case form a metal plate 24 and a magnetic one Plastic membrane 18 together the non-positive device.
- the openings 14 are sealed by the membrane 16 or 18, so that that previously flowed into the displacement 1 through the inlet openings 5 Gas can be compressed and ejected via the valve 7.
- the membrane 16 or 18 due to the pressure difference between the Vacuum in the displacement 1 and the pressure in the gear chamber 26 raised, and a Pressure equalization takes place.
- the magnetic forces generated by the non-positive device ensure that the membrane adheres securely from a defined pressure difference and thus for gas-tight sealing of the holes.
