Definitions
- Directional control valve in particular a hydraulic 3/2-way valve with an actuating unit and a valve unit operatively connected to the actuating unit, wherein the actuating unit has at least one coil and a movable armature and the valve unit contains a valve element, which is in operative connection with the armature, controls the connections between pressure-carrying channels of the valve unit and has one or more sealing bodies which correspond to one or more valve seats supported on the housing of the valve unit.
- Such a generic type directional control valve is known from DE 197 54 257 A1.
- a valve stem is attached to the armature, which is operatively connected via a spring-loaded sliding piece with the sealing body.
- This construction of the directional control valve is complex and expensive both in production and in assembly, so that simplification is desirable.
- a directional control valve in which the armature is in operative connection with a plunger, on which the sealing body is formed. Subsequently, the plunger has an extension, which is in operative connection with a further sealing body, which is formed as a ball.
- valve unit with valve element is expensive to manufacture, since the opening movement of the ball, which is not connected to the extension, is limited by an additional component.
- the use of a ball that is not radially or insufficiently guided usually leads to an impairment of the dynamic pressure curve with regard to a reduced rate of pressure change or increased fluctuations in the pressure change rate when the ball is closed.
- the object of the invention is therefore to simplify and reduce the cost of the valve unit of the directional valve with optimal hydraulic functional behavior.
- a valve body is provided, which is operatively connected to the armature, guided in the housing of the valve unit and connected to the sealing body or bodies. This results in a structural unit that is easy to manufacture with optimal function.
- a directional control valve can be provided which has only one sealing body with one or more valve seats or several sealing bodies with a plurality of valve seats.
- the valve body is formed as a molded body and made of plastic. He has projecting strips, with which he is guided in the housing. Such a valve body has a very good guidance in the housing, because the strips have a relatively large guide circumference and because the body is light. He is still easy to manufacture as a plastic molding.
- the valve body comprises a push rod, which is arranged on the side facing away from the armature of the valve body and connected to the one sealing body.
- this sealing body can be manufactured as a single part and have a centering opening into which the push rod can be inserted.
- this sealing body can be made of plastic.
- a particularly favorable mounting option arises when the push rod and a sealing body during assembly of the valve unit by means of ultrasonic welding are connected to one another.
- connection options are also adhesive, screw, press or clip connections to call. It is expedient to form the sealing body as a cone.
- the housing of the valve unit is designed as a tubular body and that the or one of the valve seats are made in one piece with the tubular body.
- valve seats are integrally formed on a pot-shaped component and that the pot-shaped component is inserted into the tubular body, preferably pressed.
- the tubular body can be advantageously designed as a tube and made of a sheet metal part, preferably made of a sheet steel part, in particular the valve seat, which is arranged in the end region of the tubular body, by forming, preferably flanging, made.
- This embodiment provides a housing of the valve unit which is inexpensive to produce.
- FIG. 2 shows a section through a sealing body according to FIG. 1
- 1 generally denotes an actuating unit and 2 denotes a valve unit.
- the actuating unit 1 has inter alia a coil 3 and an armature 4, which is guided, inter alia, in a magnetic core.
- the armature 4 further has a stop, with which it can interact with an inner housing 5 of the actuating unit 1 in operative connection.
- the inner housing 5 is partially formed as a magnetic core, since it is magnetically in operative connection with the coil 3.
- a designated 6 tubular body is used, in which a cup-shaped member 7 is pressed, which has a valve seat 8.
- a further valve seat 9 is provided, which is made in one piece with the tubular body 6.
- valve body 11 which is formed as a molded body, was made of plastic and protruding strips 12 which are in operative connection with the inner wall of the tubular body 6, so that there is a very good guidance of the valve body 11 in the tubular body 6 ,
- the valve body 11 adjoins the armature 4 and is inserted with a shoulder on the strips 12 in the tubular formed anchor 4.
- a sealing body 13 With the valve seat 8 is a sealing body 13 in operative connection, which is sleeve-shaped and arranged on the valve body 11.
- the valve body 11 further comprises a push rod 14, which is connected to a sealing body 15. This is in operative connection with the valve seat 9.
- the sealing body 15 is formed as a cone 10, which has a centering opening 16 according to Figure 2, with the cone 10 is placed centering on the push rod 14.
- the cone 10 is ultrasonically welding on the push rod 14 attached. Of particular importance is that it allows the ultrasonic welding, the Ventii redesign 11 including push rod 14 and sealing body 13 to connect with the cone 10 in the installed and assembled state in the tubular body 6 together.
- valve body 11 and the sealing body 15 shown in the exemplary embodiment is of course also advantageously applicable to hydraulic directional control valves with only one sealing body, which is in operative connection with two sealing seats.
