Valve arrangement

#This application is a 35 U.S.C. §371 National Stage Application of PCT/EP2011/001609, filed on Mar. 30, 2011, which claims the benefit of priority to Serial No. DE 10 2010 015 196.3, filed on Apr. 16, 2010 in Germany and Serial No. DE 10 2010 048 068.1, filed on Oct. 9, 2010 in Germany, the disclosures of which are incorporated herein by reference in their entirety.

#The invention relates to a valve arrangement in accordance with the preamble of patent claim 1.

#The disclosure relates to a valve arrangement.

#In the following text, different exemplary embodiments of the disclosure will be described in detail using the figures, in which:

#FIG. 1 shows a first exemplary embodiment of a valve arrangement according to the disclosure in a perspective view,

#FIG. 2 shows a special key for the first exemplary embodiment of the valve arrangement according to the disclosure in a perspective view,

#FIG. 1 shows a first exemplary embodiment of a valve arrangement according to the disclosure in a perspective view. A housing of the valve arrangement is configured as an insertion cartridge 1 which can be screwed into an adjustable pump (not shown in greater detail). Here, the insertion cartridge 1 is rotated about its center axis 6. Different connections which will be explained with reference to FIG. 3 are arranged on an outer circumference of the insertion cartridge 1. Said connections are in pressure-medium connections with two different valves which are arranged together in the insertion cartridge 1.

#Each valve has a valve bore 20, 22, which are shown in FIG. 3 and of which the end sections which are arranged on the end side can be seen in FIG. 1. Corresponding holes 2, 4 are therefore formed on the end side, which are arranged so as to lie diametrically opposite one another such that they are spaced apart from the center axis 6 of the insertion cartridge 1.

#Furthermore, additional circular-cylindrical recesses or holes 8, 10 of small diameter are arranged on the end side on the insertion cartridge 1, which recesses or holes 8, 10 lie diametrically opposite one another with regard to the center axis 6 and are offset with respect to the holes 2, 4 by 90 degrees. The spacing of the axis of the respective hole 8, 10 from the center axis 6 is greater than the spacing of the respective hole 2, 4.
