Definitions

  • the invention relates to a four-valve high pressure pump having
  • High pressure pumps of this type are currently extensively used in the application of media, particularly in the motor industry. They are therefore used, for example, to apply PVC material as an underbody sealant or wax for body cavity protection. Adhesives are also processed with pumps of this type. However, four-valve high pressure pumps are essentially also suitable for liquids and are of course suitable for areas of use other than the application of materials and also outside the motor industry.
  • the two cylinder blocks cover both the inlet housing part and the outlet housing part in the radial direction—in relation to the axis of the cylinder.
  • the different parts are braced together by means of tie rods which pass axially parallel through the cylinder blocks.
  • the object of the present invention is to construct a four-valve high pressure pump of the type mentioned at the outset in such a way that it is more readily transportable and the valves are easier to maintain.
  • the bracing of is the cylinder blocks, the inlet housing part and the outlet housing part, which is effected in the axial direction, results in the above-mentioned disadvantages. Therefore, the invention replaces this type of axial bracing by fastening the inlet housing part and/or the outlet housing part to the cylinder blocks from the side with the aid of special fastening means, for example with the aid of normal screws.
  • the bracing of the different components takes place here in the radial direction—in relation to the axis of the cylinder.
  • the cylinder blocks no longer cover the inlet housing part and/or the outlet housing in the radial direction. Therefore, the inlet housing part and/or the outlet housing part can be released from the other components of the pump part without difficulty, whether to thereby achieve a plurality of lighter parts for transportation or to gain access to the valves for maintenance purposes.
  • a particularly preferred embodiment of the invention is one in which the inlet housing part and/or the outlet housing part is pivotable about an axis extending perpendicularly to the axis of the cylinder after part of the fastening means has been released. In some cases, it is not necessary to fully remove the inlet housing part or the outlet housing part from the remaining pump part to gain access to the valves. It is sufficient to pivot it until it is possible to access the valves.
  • the media channel of the inlet housing part and/or the media channel of the outlet housing part has at least one opening which reaches as far as an outer surface and can be closed by a plug. If the plug is removed, the non-return valves in the media channel can be reached by way of the relevant opening.

  • FIG. 9 a view, similar to FIG. 8 , but with the inlet housing part pivoted away;
  • FIG. 10 the four-valve high pressure pump of FIGS. 1 to 3 and 6 with the inlet housing part pivoted away.
  • FIG. 1 in which the essential components of a four-valve high pressure pump are shown in a side view.
  • This is denoted as a whole by the reference numeral 1 .
  • It comprises a drive 2 , which can be of any design, operating for example electrically or pneumatically.
  • the drive 2 is shown only partially and schematically.
  • the actual pump part 3 Of interest within the present context is the actual pump part 3 , which is described in detail below.
  • It is in communication with the drive 2 by way of four rod-like tie rods 4 (cf. FIG. 3 ) which are guided through the pump part 2 in a manner explained in more detail below and are fastened from below by means of nuts 5 .
  • the pump part 2 comprises a cylinder 9 whereof the interior is divided into a lower working chamber 7 and an upper working chamber 8 by a piston 6 .
  • a solid cylinder block 10 and 11 is arranged in each case above and below the cylinder 9 .
  • the cylinder blocks 10 , 11 are octagonal in plan view, as shown in FIG. 3 ; the tie rods 4 pass through them.
  • Both cylinder blocks 10 , 11 have a respective transition channel 12 and 13 which opens at opposing ends to opposing side faces (end faces) and, as a result of its angled form in the central region, into the respective adjacent working chamber 7 or 8 of the cylinder 9 .
  • the piston 6 is seated on a piston rod 14 which is guided with a first portion 14 a through the transition channel 12 of the cylinder block 10 and upwardly out of this.
  • This portion 14 a of the piston rod 14 is in communication with the starting element of the drive 2 , as shown in FIG. 1 .
  • a lower portion 14 b of the piston rod 14 is similarly guided downwards through the lower cylinder block 11 and moves with its lower end region in a piston rod guide 16 , which is likewise shown in FIG. 1 .
  • a respective valve unit 17 and 18 is screwed to opposing sides of the cylinder blocks 10 , 11 .
  • Each valve unit 17 , 18 has a housing part 20 and 21 , through which a media channel 22 and 23 passes.
  • the media channels 22 , 23 extend in a vertical branch over virtually the entire vertical dimension of the housing parts 20 , 21 , but then bend at a right angle and thus lead into the side face of the housing parts 20 , 21 so that they are each flush with the adjacent ends of the transition channels 12 and 13 .
  • valve unit 17 which is illustrated on the left in both
  • FIGS. 1 and 2 is constructed as an inlet valve unit.
  • the housing part 20 associated therewith is therefore referred to below as “inlet housing part”.
  • This has an inlet 24 to which the medium to be pumped is supplied at a certain charging pressure.
  • the inlet 24 leads into the media channel 22 , more precisely at a point between two spring-loaded non-return valves 25 , 26 .
  • the valve unit 18 which is illustrated on the right in FIGS. 1 and 2 serves as an outlet valve unit.
  • the housing part 21 associated therewith is therefore referred to below as “outlet housing part”. To this end, this has an outlet 27 which starts from a point in the media channel 23 which is located between two spring-loaded non-return valves 28 , 29 .
  • the mode of operation of the pump part 2 corresponds entirely to that of the prior art and therefore does not need explaining in more detail.
  • FIG. 2 shows the pump part 2 during the downstroke of its piston 6 .
  • the inlet non-return valve 25 is closed here and the outlet non-return valve 29 is open.
  • the pumped medium is pushed downwards out of the lower working chamber by the piston 6 and flows over the transition channel 13 into the media channel 23 and through the open non-return valve 29 to the discharge point 27 .
  • the upper inlet non-return valve 26 in FIG. 2 is open; the medium can flow out of the inlet 24 into the media channel 22 , upwards from there through the non-return valve 26 into the transition channel 12 and finally into the upper working chamber 8 of the cylinder 9 .
  • the upper outlet non-return valve 28 in FIG. 2 is closed during this.
  • the non-return valves 25 , 26 , 28 , 29 alter their opening state.
  • the medium supplied by way of the inlet 24 then flows downwards in the media channel 22 and into the first working chamber 7 of the cylinder 9 from below, whilst the medium located in the second working chamber 8 arrives from the upwardly shifting piston 6 at the outlet 27 by way of the outlet non-return valve 28 .
  • the pump part 2 described is notable for the arrangement of the four valves 25 , 26 , 28 , 29 in separate valve units fastened to the cylinder blocks 10 , 11 from the outside. This design approach results in various advantages:
  • valve units 17 , 18 it is possible to remove the valve units 17 , 18 from the central pump part for transportation. This then results in assemblies with a weight which is relatively easy to handle. It is therefore possible to achieve weights in the order of magnitude of 10 kg for the assemblies, particularly when aluminium is the material used.
  • An at least equally important advantage of the described construction lies in that it allows for easy maintenance of the different valves 25 , 26 , 28 , 29 .
  • the housing blocks 20 , 21 of the valve units 17 , 18 can be easily removed from the central part, as shown schematically in FIG. 6 .
  • the valves 25 , 26 , 28 , 29 can then also be easily checked or, if required, replaced without the entire pump part 2 having to be dismantled.
  • the pump part 103 has an inlet 124 and three outlets 127 a, 127 b, 127 c.
  • This pump can be used for example so that the outlet 127 a serves as reserve whilst the outlets 127 b , 127 c lead to different consumers.
  • two inlets 224 a , 224 b and five outlets 227 a, 227 b, 227 c, 227 d, and 227 e are provided. Therefore, seven sides of the cylinder blocks 210 , 211 are occupied. It would also be essentially possible for the eighth side of the cylinder blocks 210 , 211 to be occupied by a further outlet or inlet. This is not the case in the exemplary embodiment shown in FIG. 5 .
  • the openings provided for this in the cylinder blocks 210 , 211 are instead closed by a closure plate 230 .
  • FIGS. 7 to 9 show a modified exemplary embodiment in which the pivoting movement takes place in a somewhat different manner.
  • a separate axis of rotation 333 is provided coaxially to the inlet 324 and the outlet 327 . If the four fastening screws 319 are released, the corresponding housing part 317 and 318 can be pivoted about this axis of rotation 333 as shown in FIG. 9 . The plugs leading to the media channels are again accessible and can be removed for maintenance purposes.
