Definitions

  • High pressure pumps of this type are currently used on a large scale in the application of media, especially in the automotive industry.
  • PVC material is used as underbody protection or wax for cavity sealing. Even adhesives are processed with such pumps.
  • four-valve high-pressure pumps are also suitable for liquids and, of course, suitable for applications other than the application of materials and also outside the automotive industry.
  • the two cylinder blocks cover - in relation to the axis of the cylinder - radial direction, both the inlet housing part and the outlet housing part.
  • tie rods which pass through the cylinder block axially parallel, the different parts are clamped together.
  • Object of the present invention is to provide a four-valve high-pressure pump of the type mentioned in such a way that it is better transportable and the maintenance of the valves is facilitated.
  • the invention therefore replaces this type of axial clamping by attaching the inlet housing part and / or the outlet housing part from the side to the cylinder blocks by means of separate fastening means, for example by means of normal screws.
  • the bracing of the various components takes place in - relative to the axis of the cylinder - radial direction.
  • the cylinder blocks no longer cover the inlet housing part and / or the outlet housing in the radial direction.
  • the inlet housing part and / or outlet housing part can be easily detached from the other components of the pump part, either in order to obtain in this way several lighter parts for transport, this is to get access to the valves for maintenance purposes.
  • the inlet housing part and / or the outlet housing part after releasing a part of the fastening means is pivotable about an axis perpendicular to the axis of the cylinder extending axis.
  • FIG. 1 Reference is made in which in a side view the essential components of a four-valve high-pressure pump are shown.
  • This is indicated overall by the reference numeral 1.
  • It comprises a drive 2, which may be of any construction, for example, operates electrically or pneumatically.
  • the drive 2 is shown only partially and schematically.
  • the actual pump part 3 which will be described in detail below.
  • It stands with the drive 2 via four rod-like tie rods 4 (see FIG 3) in connection, which are passed through the pump part 2 in the manner explained in more detail below and are fastened from below by means of nuts 5.
  • the pump part 2 comprises a cylinder 9, whose interior is divided by a piston 6 in a lower working space 7 and an upper working space 8.
  • a solid cylinder block 10 and 11 is arranged in each case.
  • the cylinder blocks 10, 11 are in plan view, like the FIG. 3 it can be seen, octagonal; they are pierced by the tie rods 4.
  • Both cylinder blocks 10, 11 each have a transfer channel 12 or 13, which opens with opposite end to opposite side surfaces (end faces) and due to its angled shape in the middle region in the respectively adjacent working space 7 or 8 of the cylinder 9.
  • the piston 6 is seated on a piston rod 14, which is guided with a first portion 14a through the transfer channel 12 of the cylinder block 10 and out of this up.
  • This portion 14a of the piston rod 14 is like the FIG. 1 can be seen, with the output member of the drive 2 in conjunction.
  • a lower portion 14b of the piston rod 14 is likewise passed downwardly through the lower cylinder block 11 and moves with its lower end portion in a piston rod guide 16, which is also in FIG. 1 you can see.
  • each Valve unit 17, 18 On opposite sides of the cylinder blocks 10, 11 each have a valve unit 17 and 18 are screwed.
  • each Valve unit 17, 18 has a housing part 20 and 21, which is traversed by a media channel 22 and 23, respectively.
  • the media channels 22, 23 extend in a vertical branch over almost the entire vertical dimension of the housing parts 20, 21, but then bend at right angles and open into the side surface of the housing parts 20, 21, that they each with the adjacent ends of the transfer channels 12 and 13 are aligned.
  • each valve unit 17 shown on the left is designed as an inlet valve unit. Therefore, its associated housing part 20 is hereinafter called “inlet Geotrosueteil".
  • This has an inlet 24 to which the medium to be pumped is supplied with a certain boost pressure.
  • the inlet 24 opens into the media channel 22 at a location between two spring-loaded check valves 25, 26th
  • Valve unit 18 shown on the right serves as an outlet valve unit. Therefore, its associated housing part 21 is hereinafter referred to as "outlet housing part”. This has for this purpose an outlet 27, which emanates from a position of the media channel 23, which lies between two spring-loaded check valves 28, 29.
  • FIG. 2 shows the pump part 2 during the downward stroke of its piston 6.
  • the inlet check valve 25 is closed and the outlet check valve 29 is opened.
  • the pumped medium is from the piston 6 from the bottom Working space 7 displaced downward and flows through the transfer channel 13 in the media channel 23 and through the open check valve 29 to the outlet 27th
  • FIG. 2 upper inlet check valve 26 Due to the charge pressure of the medium supplied via the inlet 24 and due to the suction effect of the piston 6 during its downward movement, this is in FIG. 2 upper inlet check valve 26 open; The medium can flow from the inlet 24 into the media channel 22, from there upwards through the check valve 26 into the transfer channel 12 and finally into the upper working chamber 8 of the cylinder 9. This in FIG. 2 Upper outlet check valve 28 is closed.
  • the check valves 25, 26, 28, 29 change their opening state. Then, the medium supplied via the inlet 24 flows in the medium channel 22 downwards and from below into the first working space 7 of the cylinder 9, while the medium located in the second working space 8 from the upward migrating piston 6 via the outlet check valve 28th reaches the outlet 27.
  • valves 25, 26, 28, 29 An at least equally important advantage of the construction described lies in the ease of maintenance for the various valves 25, 26, 28, 29.
  • the housing blocks 20, 21 of the valve units 17, 18 can be easily removed from the central part, such as this is schematically shown in FIG. 6 is shown. Then, in particular, the valves 25, 26, 28, 29 easily controlled or replaced if necessary, without the entire pump part 2 would have to be dismantled.
  • the pump part 103 has an inlet 124 and three outlets 127a, 127b, 127c.
  • this pump may be used so that the outlet 127a serves as a reserve while the outlets 127b, 127c lead to different consumers.
  • two inlets 224a, 224b and five outlets 227a, 227b, 227c, 227d and 227e are provided.
  • seven sides of the cylinder blocks 210, 211 are occupied.
  • the eighth side of the cylinder blocks 210, 211 could also be occupied by a further outlet or inlet. This is in the illustrated embodiment of FIG. 5 not the case.
  • the openings provided in the cylinder blocks 210, 211 are instead provided by a Closure plate 230 closed.
  • FIG. 10 for the embodiment of FIG. 1 is shown to remove only three of the four fastening screws 19. Then, the corresponding housing part 17 or 18 can be pivoted about the remaining screw 19 as a pivot axis. Then, the plugs 31, which close the openings 30 of the media channels 22, 23, are easily accessible and can be removed, so that the valves 25, 26 and 28, 29 can be easily reached via the media channels 22, 23 for maintenance purposes.
  • FIGS. 7 to 9 a modified embodiment is shown, in which the pivoting happens in a slightly different manner.
  • a separate axis of rotation 333 is provided coaxially with the inlet 324 and the outlet 327, respectively. If the four fastening screws 319 are released, the corresponding housing part 317 or 318 can be pivoted about this axis of rotation 333, as is the case FIG. 9 can be seen. Again, the plugs leading to the media channels become accessible and can be removed for maintenance.
