- valve unit After all, securing the unit from valve housing and electromagnet by means of Retaining plates are expensive, especially as an additional one Component the holding plate and the associated screws required are. For this reason, this proportional solenoid valve unit expensive to manufacture and complex to assemble.
- a valve unit is known from US-A-5 259 414.
- the invention has for its object the generic To design the proportional solenoid valve unit so that it consists of only a few components, if possible Standard components are simple and inexpensive can be manufactured and assembled.
- the proportional solenoid valve unit according to the invention has the receiving space of the installation housing over its Length constant diameter. This allows this recording space for example in a single process step be made by drilling.
- the recording room has neither steps nor thread. Therefore the valve housing be provided with a smooth outer wall, the sealing on the inner wall of the receiving space of the Installation housing is present. Additional sealing rings are not mandatory. Rather, the seal is through the Coverage between the walls of the receiving space of the Installation housing and the valve housing ensured.
- the Connection of the valve housing with the installation housing and the electromagnet is done by a corresponding one Flare that can be done easily.
- the invention Proportional solenoid valve unit exists thus from just a few components that are inexpensive to manufacture can be and their installation no additional Process or manufacturing steps required. Therefore, the proportional solenoid valve unit according to the invention manufactured and assembled extremely cost-effectively will.
- the proportional solenoid valve unit is used to To control or regulate the aggregate (not shown).
- a unit can be, for example, a piston-cylinder unit be, for example, part of a Power steering of a motor vehicle is.
- the proportional solenoid valve unit has an electromagnet 1 that trained in a known manner and therefore not in detail is described. It has a plunger 2 (Fig. 2), the when energizing the electromagnet 1 in the axial direction is moved. With the plunger 2, a piston 3 is against the force of a compression spring 4 shifted. The piston 3 and the compression spring 4 are accommodated in a valve housing 5, this in turn in an installation housing 6 is arranged.
- the installation housing 6 has a continuous Receiving opening 7, which are constant over its length Diameter. This allows this receiving opening 7 very easy to produce in a single step.
- the valve housing can be accommodated in this receiving opening 7 5 very easy to use. It lies with its cylindrical Wall 8 on the opening wall.
- the Installation housing 6 has on its facing away from the electromagnet 1 Side an annular projection 9, which of the receiving opening 7 is penetrated.
- the valve housing 5 projects axially over the annular projection 9.
- the valve housing 5 has none on its outer wall 8 Grooves for inserting sealing rings.
- the seal between the installation housing 6 and the valve housing 5 is due to the overlap between the walls the receiving opening 7 and the outer wall 8 of the valve housing 5 reached.
- the valve housing 5 has two working connections 10 and 11 and a pressure connection 12 located between them.
- the installation housing 6 points to the working connections 10, 11 subsequent holes, of which only in Fig. 2 the bore 13 adjoining the working connection 10 is shown.
- the pressure connection 12 is via a (Not shown) hole in the installation housing 6 with the Pump of the hydraulic system, also not shown connected. Via the pressure connection 12, the hydraulic medium fed and depending on the position of the piston 5 Working connection 10 or the working connection 11 supplied.
- the valve housing 5 faces near the electromagnet 1 opposite end on the outside an annular groove 14, in which the projection 9 of the installation housing 6 with a corresponding flange 15 engages.
- the lead 9 has such a wall thickness that the flare 15 is simple after inserting the valve housing 5 in the receiving opening 7 of the built-in housing 6 can be attached. In this way, the valve housing 5 and that Connect the installation housing 6 very easily.
- Valve housing 5 At its end facing the electromagnet 1 Valve housing 5 has a thin-walled sleeve-shaped projection 16, which has a cylindrical connecting part 17 of the Grips electromagnet 1.
- the cylindrical projection 16 is flanged diagonally inwards and thus overlaps the connecting part 17, which is conical in this area is trained. It is also possible to use the cylindrical one Projection 16 of the valve housing 5 with over its circumference to provide protruding tongues arranged in a distributed manner, which are bent obliquely inwards. This too A simple, acting in the axial direction positive connection between the electromagnet 1 and manufacture the valve housing 5.
- the projection 16 protrudes from an end face 18 of the valve housing 5, to which the connecting part 17 rests and which of a penetrates central bore 19 of the valve housing 5 becomes.
- the plunger 2 of the electromagnet 1 protrudes into the Bore 19 and lies against the end face of the piston 3.
- the piston 3 is mirror-symmetrical to its transverse central plane trained so that when installed in the Valve housing 5 is not paid attention to its position got to.
- the piston 3 has two spaced apart Ring webs 20 and 21, the width of which is slightly larger is the width of the working ports 10 and 11. In the middle position of the piston shown in FIG. 2 3, the two working connections 10 and 11 closed by the ring webs 20, 21 of the piston 3.
- Valve housing 5 At the end facing away from the electromagnet 1 Valve housing 5 with an axially projecting cylindrical Provide projection 22.
- plastically deformable tongues 23 axial incisions brought in. This allows the tongues 23 to be radial deform inwards.
- the tongues 23 serve to secure the axles the compression spring 4. By different strengths plastic deformation, the tongues 23 can be bent be that the compression spring 4 for the respective application has the required preload.
- the piston 3 is intended to be in the central position shown in FIG. 2 at a given current with which the Electromagnet 1 is acted upon.
- the working connections 10, 11 of the valve housing are in the middle position 5 through the two ring webs 20, 21 of the piston 3 closed.
- the electromagnet 1 with the appropriate current acts, whereby the plunger 2 correspondingly far extends axially from the electromagnet 1 and the piston 3 shifts to the right in Fig. 2.
- the tongues 23 now plastically bent inwards until the Ring webs 20, 21 of the piston 3, the working connections 10, 11 close. In this way, the valve unit very easy to assemble and still very easy set exactly so that at the appropriate current the work connections are also reliably closed are.
- the tongues 23 thus not only secure the Compression spring 4 in its installed position, but serve at the same time also as an adjustment means to move the valve unit in the way described to the appropriate amperage of the electromagnet. While with the conventional valve housings for axial support of the Compression spring 4 an adjusting screw is required and a corresponding thread has to be made the adjusting screw for the valve housing described as well as the production of a thread. At this Valve unit thus become an expensive component as well an elaborate and accordingly expensive production avoided without this adversely affecting the Functionality and in particular the setting of the Valve unit affects.
- the outer diameter advantageously corresponds of the piston end 24 the inner diameter of the compression spring 4, which is guided properly at this piston end becomes.
- valve unit described with the electromagnet 1 can be inexpensive from only a very few components manufacture, assemble and simple and inexpensive in it Install installation housing 6. In particular, they are not complex and expensive manufacturing process steps of the installation housing 6 and the valve housing 5 required.
