Definitions
- the invention relates to a reciprocating compressor, which can provide variable delivery quantities at the same drive speed.
- the invention aims to provide a piston compressor in a cost effective manner and reducing manufacturing costs, in which, despite variable delivery quantities as little as possible changes in components are required and therefore while maintaining the different delivery quantities as large as possible Similar parts can be used.
- a reciprocating compressor for this purpose with a piston connected via a motor-driven crankshaft and a connecting rod, which is reciprocable about a stroke in a cylinder with a closing-side cylinder head and has at least one suction valve and at least one pressure valve, which is such is designed that in a compressor with variable delivery quantity at the same drive speed such a design is provided that it comprises largely identical modular system components (equal parts) and substantially only a corresponding adjustment of the stroke of the crankshaft of the reciprocating compressor for delivery quantity variation.
- the present invention is the way, even with different delivery quantities of the reciprocating compressor largely consistent designed major components, such as the crankshaft, connecting rods, pistons, etc. to use.
- the modular system components are here designed as equal parts within a series with different delivery quantities such that they meet the requirements in terms of the largest desired delivery quantity.
- the piston compressor according to the invention only the stroke of the crankshaft of the reciprocating compressor is adapted to the corresponding desired delivery quantity. For this purpose, different measures are proposed.
- the cylinder head is pressure-tightly mounted on the cylinder.
- the cylinder head part is designed separately from the cylinder body and can also be designed as a cast part without great manufacturing difficulties.
- a valve receiving plate is preferably provided in the piston compressor according to the invention.
- This valve receiving plate limits the front side of the cylinder space formed.
- the valve receiving plate is sealed in the cylinder.
- the peripheral seal is formed by an O-ring.
- valve receiving plate is fastened by means of Riffelbundschrauben on the valve head.
- Riffelbundschrauben on the valve head.
- the design of the piston compressor according to the invention is made in such a way that the pressure in the valve head pressure walls to form pressure-separated Saugventil- and pressure valve spaces are provided, in particular, these pressure walls connect the spacers in the valve head with each other. This results in a mutual stiffening of the cylinder head part.
- the one or more pressure valve (s) are provided in the valve receiving plate, while the suction valve or the suction valves are integrated in the piston of the reciprocating compressor. This results in the cylinder head a completely separate pressure chamber, so that can be used in a preferred manner, several valves.
- Both valve head variants can be modified by changing the heights of the spacers in a simple manner.
- the piston compressor according to the invention in the case of design as a stepped cylinder on the cylinder base comprises a compensating plate (intermediate plate), so that a corresponding stroke compensation in the stage cylinder this design form or stroke compensation can be done.
- a compensating plate intermediate plate
- FIG. 1 shows a schematic sectional view through a piston compressor with variable delivery quantities at the same drive speed, which has a first stroke and is designed as a step cylinder,
- FIG. 2 shows a schematic sectional view through a piston compressor with a smaller modified stroke, in order to provide a small delivery quantity at the same drive rotational speed, whereby this preferred embodiment is also designed as a stepped cylinder,
- FIG. 3 is a schematic sectional view of an arrangement of FIG.
- Figure 4 is a schematic sectional view through a
- Embodiment of a piston compressor according to the invention wherein the pressure valves are provided in a valve receiving plate, while the suction valves are integrated in the piston,
- FIG. 5 is a sectional view similar to FIG. 3 showing the arrangement of the cylinder head, cylinder body and the assignment to the piston, the pressure valves and the pressure valve arrangement being based on the design of FIG. 4, and
- FIG Fig. 6 is a schematic sectional view of a preferred one
- Embodiment of a reciprocating compressor according to the invention which is applied as a single-acting cylinder.
- FIGS. 1, 2 and 3 there is shown a first preferred embodiment of a reciprocating compressor, generally designated 1.
- the reciprocating compressor 1 has a motor-driven crankshaft 2, a cylinder 3, a closing-side cylinder head 4, a piston 5 and at least one suction valve S and at least one pressure valve D.
- the piston 5 is connected via a connecting rod 6 with the motor-driven crankshaft 2.
- the reciprocating compressor 1 according to FIGS. 1, 2 and 3 has a design form as a step cylinder.
- the cylinder head 4 is pressure-tightly mounted on the cylinder 3 and has spacers 7.
- a valve receiving plate 8 which limits the cylinder space 9 frontally sealed by a radially acting peripheral seal 12 pressure-tight in the cylinder 3, so that regardless of the axial height of the valve receiving plate 8 always a pressure-tight completion of the cylinder chamber 9 is given.
- the peripheral seal 12 is formed in the form of an O-ring.
- the cylinder head is sealed against the cylinder 3 by means of a front seal 13.
- the valve receiving plate 8 is fixed by means of Riffelbundschrauben in the cylinder head 4.
- the valve receiving plate 8 the pressure valves D and the suction valves S on.
- the cylinder head 4 comprises pressure-separated spaces, which are associated with the suction valves S and the pressure valves D and communicating with them. These pressure walls preferably connect the spacers 7 of the cylinder head 4 with each other.
- the piston compressor design 1 of Figure 1 has a first stroke H1, which is such an embodiment, in which the stroke H1 is determined for the largest required delivery quantity of a reciprocating compressor series.
- the piston compressor according to FIG. 2 has a smaller modified stroke H2, as a result of which the delivery quantity provided by the piston compressor 1 can be reduced compared with that of FIG. It can be seen that essentially all the main functional parts of such a piston compressor 1, apart from the hub H1, H2 of the crankshaft are designed as identical parts of a modular system design form to use common parts at different delivery quantities and thereby a manufacturing technology cheaper larger quantities reach is.
- a step cylinder is realized in the reciprocating compressor 1, and for comparison with the corresponding lifting height H1, H2, an intermediate plate or compensating plate 11 is provided.
- This intermediate plate or compensating plate 11 is provided on the cylinder base of the cylinder 3.
- FIG. 5 also illustrates this embodiment variant according to FIG. 4, in which the pressure valves D in the valve receiving plate 8 and the suction valves S are integrated in the end face of the piston 5.
- FIG. 6 finally shows an embodiment variant of a reciprocating compressor 1 "in which a construction with a single-acting cylinder 3 'is provided. Therefore, the intermediate plate or compensating plate 11 shown with the aid of the preceding figures can be dispensed with without substitution, but in its basic conception this reciprocating compressor 1" designed in accordance with the above-explained embodiments. Further, in this embodiment of Figure 6 illustrates such a design, in which a plurality of pressure valves D are provided in the valve receiving plate 8, while a single suction valve S is integrated in the end face of the piston 5. Otherwise, all other details of the embodiment of the reciprocating compressor 1 "are consistent with those of the preceding details discussed, and a more detailed discussion and description thereof may therefore be omitted.
- the reciprocating compressor 1, 1 ', 1 is the fact that as many matching identical parts are present and a variable delivery quantity is substantially reduced by the fact that the stroke H1, H2 of the crankshaft 2 of the reciprocating compressor 1, 1' , 1 "is adapted and varied in a corresponding manner.
- the proposed valve receiving plate 8 can more or less in the cylinder chamber. 9 be immersed.
- the reciprocating compressor 1, 1 ', 1 “comprises a construction in the form of a modular system with components of identical construction. The corresponding choice and adaptation of the stroke H1, H2 allow the corresponding desired delivery quantity to be modified and varied.
