Definitions
- the present invention relates to a valve for controlling a fluid flow, in particular a gas flow.
- Valves for controlling a gas flow are known. These are used for example in Luftentölmaschinen in vacuum pumps.
- valves tend due to component tolerances in interaction with the partly pulsating gas flow to flutter and rattling. This can lead to various problems, such as increased wear or excessive noise. In order to avoid this flapping or rattling, there are different approaches, which are based on a tolerance compensation or damping.
- a valve for controlling a fluid flow in particular a gas flow
- the valve has a valve seat, a valve closing element, a guide element and a damping element.
- the valve closing element seals in a closed position against the valve seat. In an open position of the valve closing element, this is spaced from the valve seat and allows a flow of fluid through the valve.
- the valve closing element can be actuated between the closed and open positions in the axial direction.
- the guide element performs a movement of the closing element between the closed position and the open position.
- the damping element presses the valve closure element in the radial direction against an adjacent element and is formed integrally with the guide element.
- the damping element is formed integrally with the guide element, the damping element does not have to be manufactured separately and then mounted become. Thus, both the manufacture and the assembly of the valve are simplified.
- “One-piece” means that the guide element and the damping element are formed from one and the same material and in one piece, thus there is no material-technical interface between the guide element and the damping element Due to the fact that the damping element presses on the one hand against the valve closing element and the valve closure element on the other hand abuts against the adjacent element in the radial direction, frictional forces are produced or, in other words, a sliding contact is produced These friction forces or the sliding contact damp a movement of the valve closing element so that, as a result, the aforementioned rattling or fluttering is reduced or completely suppressed, and the axial and radial directions are perpendicular to each other.
- the guide element has a sleeve with a circular-cylindrical inner circumference, from which the damping element extends toward the middle axis of the sleeve.
- the valve closing element is guided at least partially within the guide element and along the central axis.
- the damping element may be formed integrally with the sleeve. This also includes, for example, the case that the damping element is designed in the form of a flattening of the circular cylindrical inner circumference of the guide element.
- the damping element is designed as a tongue.
- the tongue may be integrally connected at its one end to the sleeve. At the other end, ie at the free end, the tongue can press against the valve element.
- Such a tongue is easy to produce.
- the damping element may be resilient.
- the tongue can be easily formed elastic.
- the guide element and the damping element may be made of plastic.
- the guide element and the damping element are produced as a one-piece injection-molded part, in particular made of plastic. This results in a simple manufacturing process.
- the valve closing element has a valve cone and a valve stem, wherein the damping element presses against the valve stem. Due to the action of the damping element, the valve stem tilts relative to the main flow direction of the fluid flow through the valve. This tilting can lead to the valve stem coming to rest against the sleeve of the guide element at several points, resulting in a corresponding friction.
- valve stem is guided in the guide element, in particular in the sleeve thereof. As a result, the valve stem or the valve closing element can be easily guided overall.
- the guide element can form the adjacent element.
- the adjoining element may also be designed in the form of a sleeve surrounding the valve cone.
- an air de-oiling element and a vacuum pump are provided with a Heilentölelement with the valve according to the invention.
- Such vacuum pumps are used, for example, in the field of motor vehicles.
- FIG. 1 schematically shows a vacuum pump with a perspective broken and exploded view valve according to one embodiment
- Fig. 2 is a side view of Fig. 1;
- the vacuum pump 1 shows schematically a vacuum pump 1.
- the vacuum pump 1 may for example be part of a motor vehicle.
- the vacuum pump 1 comprises a perspective exploded and shown in exploded view valve 2.
- the valve 2 is adapted to control a fluid flow, in particular a gas flow. This control function may include completely shutting off the fluid flow or also reducing or increasing the flow rate of the fluid flow through the valve 2.
- the valve 2 has a valve seat 3, which is formed on a cover 4 of the valve 2.
- the valve 2 further comprises a valve closing element 8, which is composed of a valve cone 5 and a valve stem 6.
- the poppet 5 is formed at one end of the valve stem 6.
- a closed position of the valve closing element 8 the valve cone 5 seals against the valve seat 3 and thereby prevents a flow of fluid through the limited opening of the valve seat 3 7 or reduces the flow rate up to a mini mal amount.
- an open position of the valve closing element 8 the valve cone 5 is spaced from the valve seat 3 and thus allows a fluid flow through the opening 7 and thus through the valve 2 to.
- the valve cone 5 is in axial direction 9 between the closed position and the open position operable.
- the axial direction 9 is opposite to the main flow direction through the opening 7. However, it can also coincide with this.
- the valve 2 also has a guide element 1 1.
- the guide element 1 1 is composed of a first and a second sleeve 12, 13, which are interconnected by means of radial webs 14.
- the webs 14 together with the sleeves 12, 13 openings 15 for guiding fluid toward or away from the opening 7.
- the sleeve 12 has at its one end an edge 16 which serves as an abutment for one end of a coil spring 17 ,
- the coil spring 17 is supported at its other end against the valve plug 5 from.
- the coil spring 17 biases the valve cone 5 in the closed position.
- the valve stem 6 extends through the coil spring 17 and extends at its free end 21 through the sleeve 13th
- a damping element in the form of a tongue 22 is integrally formed on the sleeve 13.
- FIGS. 2 and 3 show a side view from FIG. 1 and a section III-III from FIG. 2 respectively.
- the tongue 22 presses in the radial direction 30 against the valve stem 6.
- the valve stem 6 comes at a contact point 24, which is substantially opposite to the tongue 22, in abutment with the sleeve 13.
- the thereby adjusting frictional contact provides the desired damping to at least reduce the fluttering or rattling.
- the tongue 22 extends from the inner circumference 25 of the sleeve 13 toward the central axis 23.
- the sleeve 13 is formed with a circular cylindrical inner and outer circumference 25, 26.
- the tongue 22 is integrally connected at its one end 28 with the sleeve 13.
- the free end 29 abuts against the valve stem 6.
- the tongue 22 is formed of an elastic plastic.
- the tongue 22 is produced in that incisions 27 are provided parallel to the central axis 23 on both sides of the tongue 22 in the sleeve 13.
- the tongue 22 is manufactured as a single plastic injection molded component with the sleeve 13, the webs 14 and the sleeve 12.
- abutment points 32 and / or 33 (see FIG. 1) of the valve stem 6 or of the valve cone 5 can result.
- the tilting of the valve stem 6 can lead to the valve cone 5 coming into abutment against the sleeve 12 at the contact point 33 at its edge 34, for example in the open position.
