Embodiment Construction

[0028] figure 1 A perspective view of a first exemplary embodiment with a combined valve arrangement consisting of two valves according to the invention is shown. The valve device is a pressure delivery flow regulator whose housing is designed as a cartridge valve 1 . This cartridge valve 1 can be screwed into a control pump (not shown) to save installation space.

[0029] A control pressure connection A and a tank connection T are arranged on the outer circumference of the cartridge valve 1 , while a control pressure connection P is arranged on the end face. This control pressure connection P is used for “reporting” the pump pressure of the regulating pump, wherein a bore of the control pressure connection P is assigned to each of the two valves. The control pressure connection A is used to adjust the swivel angle of the regulating pump via a (not shown) adjusting cylinder, and the tank connection T is connected to a tank (not shown).

[0030] Adjacent to the control press...

Abstract

The invention relates to a valve. The valve comprises a valve piston receiving spring force through a spring disk and a stopper for limiting the adjusting motion of the valve piston towards the opposite direction of the spring force. The spring disk is made of basically flat sheets and the stopper is a component separated from the sheets.

Description

technical field [0001] The invention relates to a valve with a spring-loaded valve piston according to the preamble of claim 1 . Background technique [0002] For valves with a spring-loaded valve piston, there are different options for supporting the spring and for limiting the adjusting movement of the valve piston. [0003] Such a valve is shown in the specification Sauer Danfoss 520L0519 Rev FN July 2009, which has a spring disk with a projection extending into the spring. In order to limit the adjusting movement of the valve piston, this projection abuts against a projection of the adjusting screw for adjusting the spring pretension which is directed opposite to this projection. [0004] Document DE 101 36 416 A1 shows a pressure delivery flow regulator in which a spring plate for limiting displacement rests against a screwed-in bushing. Furthermore, the spring disk has a protrusion extending into the spring. [0005] A disadvantage of such valves is the technical co...
