Embodiment Construction

[0038] figure 1 A first exemplary embodiment of the valve device according to the invention is shown in a perspective view. The housing of the valve device is designed as a mounting sleeve 1 which can be screwed into an adjustable pump (not shown in detail). In this case, the mounting sleeve 1 rotates about its center axis 6 . Different interfaces are set on the outer circumference of the installation sleeve 1, and these interfaces refer to image 3 to explain. These connections are in a pressure medium connection with two different valves which are jointly arranged in the mounting sleeve 1 .

[0039] Each valve has as image 3 Valve holes 20, 22 are shown, and where figure 1 Only the end section arranged on the end side can be seen here. Corresponding openings 2 , 4 are therefore arranged on the end faces, which are arranged at a distance from the center axis 6 of the mounting sleeve 1 and are arranged diametrically opposite one another.

[0040] In addition, diametric...

Abstract

A valve arrangement includes at least two valves and a housing which is configured as an installation cartridge. One of the valves is configured as a pressure regulator and the other of the valves is configured as a delivery flow regulator. The valve arrangement is configured to be inserted or screwed into a variable-displacement pump, thereby minimizing the spatial requirement of the valve arrangement.

Description

technical field [0001] The invention relates to a valve arrangement according to the preamble of claim 1 . Background technique [0002] A housing in the form of a sleeve is known in a valve arrangement according to the prior art, which can be inserted into an opening of a hydraulic system. [0003] Document DE 10 2007 044 451 A1 shows such a pressure regulating valve which has a housing in the form of a sleeve which is screwed into a connecting plate of a hydrostatic piston compressor. [0004] Document GB 2 367 095 A likewise shows a pressure regulating valve, and document DE 296 20 927 U1 shows a non-return valve in the form of a sleeve. [0005] A disadvantage of this valve is that only one valve is accommodated in the sleeve. [0006] Furthermore, it is known from the prior art to combine two valves in a housing. Document DE 101 36 416 A1 shows such a combination of a pressure regulating valve and a delivery flow regulating valve. The housings of the two valves are ...
