Definitions

  • the invention relates to a cylinder head for a compressor, in particular a reciprocating compressor for use in motor vehicles, which is suitable for compressing a compressible working medium, in particular air, for use in a compressed air supply device of a motor vehicle.
  • Reciprocating compressors or compressors or air compressors are used to compress gases, e.g. B. air, which is used as a working medium for operating various units in a motor vehicle.
  • the reciprocating compressor essentially consists of a main body, or crankshaft housing or cylinder housing, in which at least one reciprocating piston is arranged, and a cylinder head.
  • ambient air is sucked into the piston chamber via an inlet duct, compressed and then passed on via a duct.
  • the compressed air is passed on to a further or subsequent compressor stage, where it is compressed further.
  • the compressed air is then fed into the compressed air tank via an air treatment unit.
  • a cylinder head is known, for example, from DE 10 2015 225 069 A1 and is composed of several components which are arranged one above the other in layers. The components form different channels or chambers through which air or a cooling medium, in particular cooling water, flows.
  • the channel guide through the cylinder head or through the individual components of the cylinder head is selected such that the channel is as long as possible and passes as close as possible to the coolant channel. Due to the compact design of the cylinder head, however, it cannot be avoided that heat exchange takes place between the air flows that are led through the cylinder head and have different temperatures. The heat transfer between the air flows at different temperatures takes place via the partition walls of the ducts. Due to the metallic design of these partitions, the thermal conductivity is very good. The disadvantage is that this heat transfer negatively affects the efficiency of the reciprocating compressor.
  • the object of the invention is to improve the cylinder head structure in such a way that the efficiency of the reciprocating compressor is increased.
  • a cylinder head for a reciprocating piston compressor for compressing a compressible working medium comprising a cylinder cover and a valve carrier plate, is proposed, which is constructed as follows and has the following features.
  • An intermediate element is arranged between the cylinder cover and the valve support plate and a plurality of channel sections and / or chambers are arranged or formed by the valve support plate and the intermediate element and between the cylinder cover and the intermediate element, through which different media flows can be conducted.
  • one or more insulating chambers are provided in the cylinder head, which thermally isolate the duct sections and / or karmers from one another at least in regions.
  • an inlet space and an outlet space are provided, between which the insulating chamber is arranged.
  • further insulation chambers can also be arranged between different temperature ranges.
  • an exhaust port can be provided in the cylinder head, the insulating port thermally insulating the intake space and the exhaust space at least in regions from the exhaust port.
  • the insulating chambers can essentially be formed by depressions in the valve carrier plate and / or in the cylinder cover. The depressions are then closed by means of the intermediate element.
  • the isolation chambers preferably contain enclosed ambient air. No additional work step needs to be planned for assembly.
  • the insulation chambers can also be filled with an insulation material or contain a vacuum.
  • the intermediate element has connection openings which connect the channel sections and / or chambers in the valve carrier plate and in the cylinder cover to one another.
  • the air flow and / or the cooling medium flow can thus move from one level to another.
  • the intermediate element can also be a sealing element.
  • the cylinder head can be a cylinder head for a multi-stage reciprocating compressor, the inlet chambers of the compressor stages being arranged between the outlet chambers of the compressor stages.
  • an insulating chamber can be arranged between the outlet chamber and the inlet chamber of the second compressor stage and / or between the inlet chamber of the second compressor stage and the inlet chamber of the first compressor stage.
  • FIG. 2 top view of the cylinder head (section A-A)
  • FIG. 3 Alternative structure for a cylinder head
  • Figure 1 shows a two-stage reciprocating compressor 1 or compressor with Zylin derkopf 2 in section. The course of the cut can be seen in FIG. 2.
  • the cylinder head 2 is composed of the valve support plate 5, the cylinder head cover 7 and an intermediate element 6 arranged between them.
  • FIG. 2 shows a plan view of the cylinder head 2, the section A-A being shown in FIG.
  • the reciprocating compressor 1 has water cooling which runs through the cylinder housing 3 and through the cylinder head 2.
  • FIGS. 1 and 2 As can also be seen from FIGS. 1 and 2, several channel sections 8.1, 10 and several chambers 14.1, 14.2, 15.1 and 15.2 are present between valve carrier plate 5 and intermediate element 6 and between cylinder cover 7 and intermediate element 6. Furthermore, there are several insulating chambers in the cylinder head 2
  • the insulating chambers 9.1 and 9.2 are arranged such that, in particular, the duct section 10, through which the hot compressed air of the second compressor stage 18 is directed to the outlet opening 20, from the chambers
  • 14.1, 14.2, 15.1 and 15.2 is isolated. This prevents undesired heating of the intake air, in particular the cool ambient air, and the precompressed air which is conducted from the first compressor stage 17 to the second compressor stage 18.
  • the isolation chambers 9.1 and 9.2 are closed cavities which are essentially formed by depressions in the valve carrier plate 5 and in the cylinder cover 7 and are closed by the intermediate element 6.
  • the insulating chambers 9.1 and 9.2 are filled with ambient air that was enclosed during assembly
  • Connection channel 19 are once in contact with the cooling channel 8.2 and also have a large cooling surface with respect to the ambient air.
  • Figure 3 shows an alternative structure for a cylinder head 1. This differs essentially in the arrangement of the channels and chambers.
  • the insulating chambers 9.3 are arranged here between the connecting duct 19 and the compressed air duct 10.
  • the insulating chamber 9.3 is incorporated in the valve support plate 5 and is closed by the sealing element 4.

Abstract

L'invention concerne une culasse (2) destinée à un compresseur à pistons alternatifs pour comprimer un milieu de travail compressible. Ladite culasse comprend un couvercle de cylindre (7) et une plaque de support de soupape (5) qui est construite comme suit et qui présente les caractéristiques suivantes. Un élément intermédiaire (6) est disposé entre le couvercle de cylindre (7) et la plaque de support de soupape (5), et une pluralité de portions de conduit (8.1, 10) et/ou de chambres (14.1, 14.2, 15.1, 15.2) sont disposées entre la plaque de support de soupape (5) et l'élément intermédiaire (6) et entre le couvercle de cylindre (7) et l'élément intermédiaire (7), ou sont formées par ceux-ci et permettent de guider différents flux de milieu. Pour améliorer l'efficacité du compresseur à pistons alternatifs, des chambres isolantes (9.1 ... 9.3) sont prévues dans la culasse (2), qui isolent thermiquement les portions de conduit (8.1, 10) et/ou les chambres (14, 14.2, 15.1, 15.2) les unes des autres au moins par endroits.
