Definitions
- the present invention relates to a valve for controlling a fluid flow and a steering system for a vehicle.
- Valves are known in the art which switch / control / direct a fluid flow in hydraulic or pneumatic systems.
- valves For controlling a fluid flow, valves are used which comprise an inner and a middle sleeve and a valve housing.
- the inner sleeve can be rotated to the middle sleeve, whereby various switching states of the valve can be realized.
- the connections for the supply and discharge of the fluid are arranged. Since the middle sleeve with respect to the outer sleeve / the valve housing can rotate over 360 °, takes place the supply and discharge of the fluid via annular grooves. To ensure trouble-free operation, the transitions are, for example, rounded. For this purpose, in addition to the radial machining and axial machining must be made.
- Initial state for example, the fluid flow is passed directly into the return.
- One object is therefore to provide a valve which can be easily manufactured and / or whose "hydraulic center” is easily adjustable or which is capable of automatically setting its "hydraulic center”.
- a fluid flow control valve comprising: an inner sleeve having a
- Control surface and a central sleeve wherein a first movement of the inner sleeve to the central sleeve is vorrisebar, wherein the valve has a control piston, wherein the first movement, a second movement of the control piston takes place, whereby the valve is converted into a switching state.
- the arrangement of a control piston can be dispensed with axial machining of inner walls to direct the flow of fluid, which significantly simplifies the manufacturing process of the valve.
- a steering system for a vehicle comprising a valve according to one of claims 1 to 8.
- a valve is provided, wherein the first movement is a rotation / rotational movement / axial displacement and / or wherein the second movement is a rotation / rotational movement / axial displacement, the axial displacement being a displacement in the direction of Longitudinal axis of the valve is.
- a valve is provided, the valve having means for pressing the control piston against the control surface.
- a valve is provided, wherein the means is designed to act along the longitudinal axis of the valve.
- the automatically adjustable starting situation can be defined as "hydraulic center”.
- a valve is provided, wherein the means is a spring.
- the means is a spring.
- a valve is provided, wherein the control surface is inclined to the longitudinal axis of the valve and / or wherein the control surface releases more space or less space in the direction of the longitudinal axis by the first movement for the control piston.
- a valve is provided, wherein the valve 1, 2, 3, 4, 5, 6, 7, 8 or any number of control piston has. Both by the use of any number of control pistons, as well as the design / mechanical design of the / each control piston, the valve can be scaled in terms of its fluid flow according to the requirements.
- an idea of the invention can be considered to provide a valve that can be switched by a control piston. As a result, can be dispensed with a complex processing of inner walls of the sleeves of the valve.
- the individual features can also be combined with each other, which can also be partially beneficial effects that go beyond the sum of the individual effects.
- FIG. 4 shows a longitudinal sectional illustration of a section of the valve according to the invention
- FIG. 5 shows a cross-sectional view of the valve according to the invention
- Fig. 6 curves illustrating the relationship between torque and pressure.
- Fig. 1 shows a valve of the prior art with a middle sleeve 2 and an inner sleeve 1, wherein the inner sleeve 1 to the middle sleeve 2 can be rotated.
- the middle sleeve 2 has longitudinal grooves 15, which are required for proper inflow and outflow of the fluid.
- the longitudinal grooves 15 require in addition to a radial machining and axial machining of the inner wall of the middle sleeve 2, which is a high manufacturing expense.
- Fig. 2 shows a valve according to the invention with an inner sleeve 5, which is rotatable and a central sleeve 14.
- On a valve housing 7 supply and discharge lines 6, 12 are arranged for the fluid.
- control piston 10 can be mounted, which can be held by springs 9 in the axial direction, ie in the direction of the longitudinal axis 20 of the valve, under tension and which bear against a control surface 19.
- the control surface 19 may change, for example, in its inclination at the bearing point of the control piston 10 and the control piston 10 can be moved in the axial direction 20.
- the axial displacement of the control piston 10 may result in a circuit of the valve.
- Fig. 3 shows the valve according to the invention in an exploded view with the inner sleeve 5 and the middle sleeve 14, wherein in the middle sleeve 14, the control piston 10 are arranged.
- the control piston 10 are held by springs 9 under mechanical tension and pressed against the control surface 19.
- the control surface 19 By turning the inner sleeve 5, the control surface 19 also rotates and the control pistons 10 can be displaced in the axial direction.
- 4 shows a longitudinal section of a section of a
- Valve according to the invention with the inner sleeve 5, the middle sleeve 14 and the control piston 10.
- the control piston 10 are pressed by springs 9 against the control surface 19 of the inner sleeve 5.
- the control surface 19 also shifts and the control pistons 10 can be pushed down or the control surfaces 19 can open space / space upward and the control pistons 10 can be pushed upwardly by the springs 9. This therefore results in an axial displacement of the control piston.
- the axial displacement can be used to connect / disconnect annular grooves 11, 21, whereby switching states of the valve can be realized.
- FIG. 5 shows the valve according to the invention in a cross-sectional view with the
- Control piston 10 which are mounted within the middle sleeve 14.
- a mechanical stop 13 is shown, which ensures that a maximum
- Fig. 6 is a diagram showing a relationship between a torque M exerted on the inner sleeve 5 and a pressure P resulting thereby within the system.
- the system may be pneumatic or hydraulic. It is shown that advantageously by varying the spring characteristics (soft / stiff spring) a different characteristic 23, 24 can be selected. When selecting the characteristic curve 23 ("soft" spring) results from a low torque on the inner sleeve 5 already a high
