Definitions
- the invention relates to a piston-cylinder unit, in particular for a compressor for generating a pressure fluid, with a cylinder, a piston, which is between a first piston position in which the cylinder volume enclosed by the piston and the cylinder is maximum, and a second piston position, in which this cylinder volume is minimal, can be moved back and forth in the axial direction of the cylinder, and a fluid bearing provided between the piston and the cylinder, which supports the piston in the cylinder in an axially movable manner and which encircles the circumference of the piston at least over part of the axial extent of the cylinder Determines surrounding piston-side bearing surface, the fluid bearing having a plurality of outlet nozzles provided for the fluid in the inner peripheral wall of the cylinder.
- Such a piston-cylinder unit is known from US 5,525,845 A.
- outlet nozzles are provided in the cylinder wall, which support the piston both in its first piston position and in its second piston position. To make this possible, they are Outlet nozzles relatively far from the cylinder bottom, that is, from the front inner wall of the cylinder bore. This has the consequence that the fluid cushion formed between the piston circumference and the inner cylinder circumference for mounting the piston in the cylinder in the region of the front circumferential region adjacent to the piston head becomes weaker the further the piston moves into its second piston position, that is to say into the compression position.
- a piston-cylinder unit is known from JP 2002-349 435 A, which is driven by a linear motor and in which piston-free pistons are guided freely on a gas cushion.
- the circumference of the piston is provided with a circumferential groove.
- This circumferential groove is intended to reduce the risk of the piston tipping in the cylinder.
- the circumferential groove not only weakens the transverse force disadvantageous for the bearing of the piston, but also the air bearing as a whole, so that the effect of the circumferential groove on the air bearing is rather disadvantageous.
- the object of the present invention is therefore to design a generic piston-cylinder unit in such a way that even if the piston moves into the compression position or is in the compression position, the piston is adequately and reliably supported in the cylinder and thus is safe against lateral deflection of the piston is guaranteed.
- This object is achieved by a piston-cylinder unit with the features specified in claim 1.
- first outlet nozzles supply the front or middle region of the piston-side bearing surface with respect to the piston longitudinal extension and second outlet nozzles supply the pressurized fluid with the middle region of the piston-side bearing surface with respect to the piston longitudinal extension reliable storage and radial positioning of the piston in the cylinder, without the piston coming into contact with the cylinder.
- the arrangement of the outlet nozzles in the central area or in the front and middle area ensures that the bearing center of gravity remains in the middle or front area of the piston when pressure enters the compression space into the bearing gap surrounding the piston and at most only moves slightly to the rear, which means that Reliable radial support of the piston via the bearing fluid in the middle and also in the front area of the piston is ensured, so that the influence of the pressure in the compression space on the pressure prevailing in the bearing gap is significantly reduced compared to conventional solutions.
- the nozzle arrangements are arranged in such a way that outlet nozzles are also provided in the region of the inner peripheral wall of the cylinder which the piston is opposite in the second piston position but not in the first piston position.
- a fluid cushion is reliably formed between the inner circumferential wall of the cylinder and the outer circumferential wall of the piston even in the compression state, without this being displaced from the cylinder volume by the penetration of compressed fluid.
- the piston is in the second piston position, that is in the Compression position of the piston, more reliably supported on the fluid cushion against the inner circumferential wall of the cylinder.
- the outlet nozzles are arranged in such a way that, when the piston is in its second piston position, first outlet nozzles pressurize the front area of the piston-side bearing surface with respect to the longitudinal extension of the piston, and second outlet nozzles for the region of the piston-side longitudinal extension or center of the piston-side bearing surface with pressurized fluid supply. If the outlet nozzles are provided in the front and rear region of the piston-side bearing surface, the piston is supported in a particularly uniform manner in the compression position thereof
- first outlet nozzles are provided in the front region and the second outlet nozzles in the central region of the piston-side bearing surface, as a result of which the bearing center of gravity extends forwards, that is to say toward the piston head.
- a higher pressure is built up in the fluid bearing between the piston and the cylinder in the area of the front end of the annular gap between the piston and the cylinder, i.e. towards the cylinder volume, which offers a higher resistance to the compression pressure in the cylinder volume and thus even better prevents compressed pressure fluid from flowing out of the Cylinder volume penetrates into the bearing gap.
- Outlet nozzles arranged so that when the piston is in its first piston position, the second outlet nozzles also the area of the piston-side bearing surface that is at the front with respect to the longitudinal extension of the piston and the third outlet nozzle that is located at the rear of the piston-side bearing area with respect to the longitudinal extension of the piston Supply pressure fluid.
- These optionally provided third outlet nozzles in the rear area can improve the support of the piston in its retracted position.
- the fluid bearing is formed by a gas pressure bearing, the outlet nozzles being formed by gas outlet nozzles; an advantageous and particularly preferred embodiment is that of an air bearing.
- a plurality of outlet nozzles preferably each form nozzle arrangements.
- the nozzle arrangements are preferably spaced apart from one another in the axial direction of the piston-cylinder unit and are preferably designed in a ring shape around the cylinder axis. This creates a particularly uniform fluid or gas cushion between the piston and the cylinder.
- each nozzle ring has a plurality of outlet nozzles which are evenly spaced apart in the circumferential direction.
- the outlet nozzles are preferably formed by microholes drilled by means of a high-energy jet, which are further preferably conical, the narrowest cross-section of which is located at the mouth in the cylinder-side bearing surface.
- the microholes created in this way create a fluid or gas cushion of high uniformity and high load-bearing capacity.
- microholes are preferably drilled using a laser beam.
- the pressure fluid for supplying the outlet nozzles is derived from a fluid flow generated by compression of the cylinder volume, for example from the outlet channel, a simple construction of the piston-cylinder unit can be achieved and at the same time an additional pressure generator for the pressure fluid for supplying the outlet nozzles can be achieved be dispensed with, which contributes to the cost-effective production of such a piston-cylinder unit.
- This piston-cylinder unit is particularly preferred when the piston for the reciprocating drive is acted upon by a movable part of a linear drive.
- a particularly noteworthy and advantageous application of the piston-cylinder unit according to the invention takes place in a compressor for generating a pressure fluid, preferably in a linear compressor driven by a linear motor.

- Such an asymmetry can not only be achieved by providing a different number of
- Outlet nozzles can be reached in the front or rear area of the cylinder-side bearing surface 15, but also, for example, in that the outlet nozzles in the front area of the cylinder-side bearing surface 15 have a larger nozzle diameter and thus a larger one
- the piston-cylinder unit 1 shown is part of a piston working machine in which the expelled fluid is gaseous, as is the case with a compressor, for example. In principle, however, the invention can also be used in other piston working machines, such as in internal combustion engines or pumps.
- Part of the ejected gaseous fluid is passed from the outlet channel 24 through a connecting channel 28, which is provided in the cylinder head 23 and in the housing 21 of the cylinder 2, into ring channels 30, 32, 34, which are also provided in the housing 21 of the cylinder 2 and which surround the cylinder bore 10 in a ring.
