Description

Existing technology

[0001] The present invention relates to a valve unit and a vehicle.

[0002] There are currently many different solutions for controlling volume and / or fluid flows in the automotive sector. Due to the increasing number of targeted fluid flow manipulations in the automotive sector and the increasing quality and performance requirements, the demand for innovative and robust volume flow control methods is increasing.

[0003] The continuous pursuit of weight reduction to reduce consumption and increasing competition in the automotive sector are leading to cost pressures and, as a result, an ever-increasing demand for inexpensive and efficient vehicle components. Summary of the Invention

[0004] The valve unit according to the invention having the features of claim 1 has the advantage over known solutions that a significantly increased volume flow can be provided, since the fluid flow can be significantly increased by the first and second recesses.

[0005] Another advantage is that only the displacement element can be adjusted, while all other components of the valve unit remain essentially unchanged. This reduces the possibility of errors because identical parts can be used. Furthermore, the required installation space for such a valve unit can be significantly reduced compared to previous solutions.

[0006] According to the present invention, this is achieved by the valve unit comprising an actuator, a displacement element, a sleeve element, and a spring element. Furthermore, the displacement element is displaceably arranged in the sleeve element, wherein the spring element is configured to press the displacement element toward the actuator, wherein the actuator is configured to deflect the displacement element by a predetermined value relative to the spring element, wherein the displacement element comprises a first recess and a second recess, wherein the valve unit is configured to provide a predetermined volume flow through the displacement element by means of the first recess and the second recess when the displacement element is deflected by the predetermined value.

[0007] In other words, in the case of substantially the same valve lift, by providing two recesses or two parallel cross sections, the volume flow through the valve unit can be significantly increased, wherein at the same time, at least one connection end can be present on the output side of the valve unit, and at least one connection end can also be present on the input side of the valve unit. The term "actuator" should be understood broadly and therefore, for example, includes magnetic, mechanical or similar actuators. Therefore, a parallel connection of two recesses is generated to control the volume flow. The actuator can, for example, be a magnetic actuator, etc., which can deflect or control the shift element. By controlling the shift element or deflecting the shift element to a predetermined value, for example, a valve lift of 3mm can be set. Further preferably, when the shift element deflects a predetermined value, the shift element can set a predetermined volume flow through the valve unit by means of the first recess and the second recess. Further preferably, the valve unit with the shift element can also be used as a switching valve and / or a proportional valve.

[0008] The dependent claims reveal preferred developments of the invention.

[0009] Preferably, the sleeve element has a third recess and a fourth recess, wherein the first recess and the second recess of the displacement element substantially overlap with the third recess and the fourth recess of the sleeve element when the displacement element is deflected by the predetermined value.

[0010] The advantage of this embodiment is that a volume flow through the valve unit can be increased, wherein the third and fourth recesses are particularly designed such that they form the connection ends of the valve unit. In this context, "substantially" may mean that the position deviation of the first recess relative to the third recess and / or the position deviation of the second recess relative to the fourth recess is particularly up to 50 mm.

[0011] It is further preferred that the first recess comprises at least one first slot in the wall of the displacement element, wherein the second recess comprises at least one second slot in the wall of the displacement element, wherein the first slot and the second slot are arranged substantially parallel to each other and are configured to provide a predetermined volume flow.

[0012] The advantage of this embodiment is that the manufacturability of the displacement element can be significantly simplified by the substantially parallel slots, thus reducing the manufacturing costs. "Substantially parallel" particularly refers to deviations of ±10°, particularly manufacturing-related tolerances.

[0013] It is further preferred that the first recess comprises at least one third slot in the wall of the displacement element, wherein the second recess comprises at least one fourth slot in the wall of the displacement element.

[0014] The advantage of this embodiment is that the two slots are respectively provided in the first recess and the second recess so that the two recesses can be connected by means of a web, thereby further improving the stability of the displacement element.

[0015] More preferably, the cross section The system includes at least a first slot, a second slot, a third slot, and a fourth slot and is configured to provide a predetermined volume flow.

[0016] The advantage of this embodiment is that the targeted arrangement of the four slots in the cross section allows the volume flow to have lower turbulence, thus further increasing the efficiency of the valve unit.

[0017] It is further preferred that the first recess has a plurality of first holes and the second recess has a plurality of second holes, wherein the plurality of first holes and the plurality of second holes are configured to provide a predetermined volume flow.

[0018] An advantage of this embodiment is that the torsional rigidity of the displacement element can be further improved by arranging the plurality of first holes and second holes to form the first recess and the second recess.

[0019] Preferably, the sleeve element has a first connection end and a second connection end, wherein the displacement element is configured to reduce and / or stop fluid flow between the first connection end and the second connection end when the displacement element is not deflected.

[0020] This embodiment has the advantage that different components (eg working connections, tanks, etc.) can be arranged on the first and / or second connection element, so that the fluid flow between these two components can be controlled accordingly.

[0021] Further preferably, the actuator is configured to generate a magnetic force to deflect the displacement element relative to the spring element by a predetermined value.

[0022] This embodiment has the advantage that a particularly low-wear form of deflection can be provided by means of magnetic forces or magnetic actuators.

[0023] It is further preferred that the displacement element has a plurality of recesses in order to provide a predetermined volume flow.

[0024] The advantage of this embodiment is that the predetermined volume flow can be defined in a targeted manner by adjusting the plurality of recesses.

[0025] Another aspect of the invention relates to a vehicle having a valve unit as described above and below. BRIEF DESCRIPTION OF THE DRAWINGS
