• the invention relates to a four-valve high-pressure pump with a) a drive; b) a pump part, which in turn comprises: ba) a cylinder; bb) two cylinder blocks arranged on the end faces of the cylinder, through each of which a transfer passage extends, which opens at opposite ends into an outer surface of the cylinder block and communicates in the central region with the interior of the cylinder; c) an inlet housing part comprising: ca) an inlet for the medium to be pumped; cb) a communicating with the inlet media channel in which both sides of the mouth of the inlet in each case a check valve is arranged and communicates at its opposite ends in each case with an over-channel of a cylinder block; d) an outlet housing part comprising: da) an outlet for the medium to be pumped; db) a communicating with the outlet media channel in which both sides of the discharge point of the outlet in each case a check valve is arranged and communicates at its opposite ends in each case with a transfer channel of
• 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
• the tensioning in the axial direction of the cylinder blocks, the inlet and the outlet housing part leads to the abovementioned disadvantages.
• 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.
• Particularly preferred is an embodiment of the invention in which 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 Zy Linders extending axis. In some cases, to gain access to the valves, it is not necessary to completely remove the inlet housing part or the outlet housing part from the remaining pump part. It is sufficient to pivot it until access to the valves is possible.
• the media channel of the inlet housing part and / or the media channel of the outlet housing part has at least one opening reaching up to an outer surface, which can be closed by a plug.
• the plug When the plug is removed, the check valves in the media channel can be reached via the opening in question.

• FIG. 5 shows a section, similar to FIGS. 3 and 4,
• FIG. 6 schematically shows the manner in which a valve unit can be removed from the pump part of the high-pressure pump
• Figure 7 is a view similar to Figure 1 of a fourth

• 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
• the pump part 2 comprises a cylinder 9, the interior of which is divided by a piston 6 into 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 the plan view, as shown in Figure 3, 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. As can be seen from FIG. 1, this section 14a of the piston rod 14 is connected to the output member of the drive 2.
• a lower portion 14b of the piston rod 14 is similarly passed down through the lower cylinder block 11 and moves with its lower end portion in a piston rod guide 16, which is also seen in Figure 1.
• each Valve unit 17, 18 has a housing part 20 and
• 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.
• the valve unit 17 shown on the left in each of FIGS. 1 and 2 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 in FIGS. 1 and 2 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 downwards and flows through the transfer channel 13 into the media channel 23 and through the open check valve 29 to the outlet 27.
• the inlet check valve 26 which is upper in FIG. 2 is opened; the medium can flow from the inlet 24 into the media channel 22, from there up through the check valve 26 into the transfer channel 12 and finally into the upper working space
• the peculiarity of the pump part 2 described lies in the arrangement of the four valves 25, 26, 28, 29 in the outside of the cylinder block 10, 11 attached separate valve units.
• this construction there are several advantages: Firstly, it is possible to remove the valve units 17, 18 from the central pump part for transport. It then results in assemblies with a weight that is relatively easy to handle. In particular, when using aluminum as a material so weights for the assemblies of the order of 10 kg be achieved.
• 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 , as shown schematically in FIG. Then, in particular, the valves 25, 26, 28, 29 can be easily checked or, if appropriate, exchanged without the entire pump part 2 having to be dismantled.
• FIGS. 4 and 5 Two such examples are shown in FIGS. 4 and 5.
• the pump portion 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.
• 210, 211 are occupied by a further exit or inlet. This is not the case in the illustrated embodiment of Figure 5.
• the openings provided in the cylinder blocks 210, 211 are instead provided by a Closure plate 230 closed.
• a modified embodiment 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 can be seen from FIG. Again, the plugs leading to the media channels become accessible and can be removed for maintenance.
