Definitions
- the invention relates to a pump, in particular a power steering pump for motor vehicles, having a flow control valve and a valve sleeve, which has inflow openings to the flow control valve and a pressure connection to a hydraulic consumer.
- a pump in particular power steering pump for motor vehicles, having a flow control valve and a valve sleeve, which inlet openings for flow control valve and / or a passage opening for a throttle point and a pressure connection to a hydraulic consumer, wherein the valve sleeve is designed as a sleeve and by a securing device is positioned axially in the pump housing.
- valve sleeve as a plug-in sleeve has the advantage that the insert sleeve can be used precisely angle-oriented in the pump housing. Furthermore, no threading forces of the thread deforming effect on the valve sleeve and on the pump housing.
- a preferred embodiment of the pump is characterized in that the valve sleeve has at least one transverse bore, which is positioned to a discharge bore in the pump housing.
- the execution of the insert sleeve thus allows the Use only a single transverse bore, since it can be positioned to be mounted to the housing and therefore not a plurality of transverse bores are necessary as in a screw-in, so that a sufficient flow cross-section can be made to Abströmbohrung the pump housing.
- a pump is preferred in which the securing device is represented by a flange attached to the pressure line.
- the pressure line can also be mounted in an angle-oriented manner, since the flange predetermines the direction of the pressure line and certain positions in the engine compartment of a motor vehicle can therefore be maintained.
- a pump according to the invention is characterized in that the flange is welded or soldered or pressed or screwed to the pressure line.
- Another pump according to the invention is characterized in that the flange has a flat mounting surface. Furthermore, a pump is preferred in which the flange has an angled mounting surface. This has the advantage that the space for a fastening means of the flange can be variably fixed to the housing.
- a pump is preferred in which the flange mounting surface is secured by at least one screw on the pump housing. After tightening the screw so that both the hydraulic line and the Ventileinsteckhülse is attached and secured in the axial direction of the Ventileinsteckhülse.
- Another pump according to the invention is characterized in that the securing device is represented by a caulked flange in the pump housing.
- a further advantage of the insertion sleeve is that the insertion sleeve can be centered relative to the valve piston, in particular if the insertion sleeve has a funnel-shaped valve seat for the valve piston, whereas a Einschraubpatrone by the possible offset between the thread and the funnel-shaped valve seat to a widening of the valve bore in Housing and can lead to an offset between the valve piston and the valve seat.
- Figure 1 shows a cross section through a power steering pump with an inventive
- FIG. 2 shows a plan view of the flange connection
- FIG. 3 shows an angled flange connection on a pump housing
- FIG. 4 shows a valve sleeve with a caulked flange in the pump housing.
- FIG. 1 shows a cross-section of a power steering pump 1 is shown with a pump rotation group and a valve assembly. From the rotation group, a so-called control plate 3 can be seen within the pump housing 5, wherein the control plate 3 contains suction kidney 7 and pressure kidney 9 for a double-stroke vane pump. The rotor and the wings of the wing gel cell pump are not shown here.
- a valve assembly 11 is shown, which can perform the combination function of a flow control valve and a pilot operated pressure relief valve.
- a valve piston 15 is slidably disposed. The valve piston 15 bears with a sealing edge 17 against an approximately funnel-shaped seat of a valve sleeve 19.
- the valve sleeve 19 in turn is mounted insertable in an enlarged part 21 of the valve bore 13.
- the valve sleeve 19 also has a passage opening 23, in which a partially conical pin 25 of the valve piston 15 with the passage opening 23 is a variable throttle point for the consumer oil flow.
- the consumer oil flow is supplied through the pressure line 27 to the consumer, for example, a hydraulic power steering.
- the pressure line 27 is inserted in the region 29 of the valve sleeve 19 and additionally provided with a seal 31.
- the pressure line 27 also has a flange 33, which is here, for example by means of a weld on the pressure line 27, fixed and secured with a screw 35 in the housing 5.
- a discharge bore 37 leads into the valve region, where a corresponding inflow opening 39 of the valve sleeve 19 of the discharge bore 37 is juxtaposed in the housing. Due to the fact that the valve sleeve 19 can be positioned as an insertion sleeve relative to the outflow bore 37 in the housing 5, a clearly defined transitional cross section always results between the outflow bore 37 and the valve sleeve 39, which is not possible in the prior art by the screwed-in sleeves used therein when screwing the corresponding positions of the inflow openings 39, depending on the thread and Anschraubkraft different.
- the valve assembly in the upper part of the housing 5 further comprises a pressure relief pilot with a pilot valve sleeve 41, in which a pilot valve cone 43 is sealingly mounted in a valve seat 45 and is pressed by a spring 47 into the valve seat.
- a pilot valve cone 43 When the adjustable maximum pressure is exceeded by the pretensioning force of the spring 47, the valve cone 43 opens by lifting itself off from the seat 45, thereby producing a pilot-operated pressure limiting valve with the valve piston 15.
- the valve piston 15 which is pressed by a spring 49 in the sealing edge 17, as a flow control valve piston and limits the flow flowing to the consumer to a certain value.
- Such Stromregelventil- and Druckbegrenzungsvent.il- functions are well known from the prior art and should therefore not be further explained here.
- the insertion sleeve 19 can be positioned to the discharge bore 37 and, if necessary, only a single inflow opening 39 is required, while in the prior art several inflow openings have to be used as outflow openings in order to realize the necessary hydraulic opening cross-sections. Furthermore, acting on the valve sleeve 19 and thus also on the receiving bore 21 no screwing, which can lead to deformations and decentrations in the prior art.
- An additional advantage provides the pressure line 27 with the welded flange 33, which can be positioned in the appropriate necessary mounting position for the eventual space in the engine compartment of a motor vehicle and thus allows a positionally correct mounting without screwing the pressure line.
- the axial fixation on the pump housing for both the pressure line 27 and the valve sleeve 19 is effected by the separate screw 35 between the flange 33 and the pump housing fifth
- FIG. 2 the flange 33 from FIG. 1 is shown by way of example in plan view.
- the pressure line 27 is shown cut and secured by the weld 37 on the flange 33.
- the flange 33 is fastened in the illustrated position on the pump housing not shown here by a single screw 35.
- the position of the flange 33 to the course of the pressure line 27, as shown in Figure 1, is thus set for mounting in the motor vehicle.
- a flange 51 is shown with an angled mounting surface 53 alternatively.
- another surface of the housing 5 can be used as the mating surface of the pressure line 27 for mounting mounting, if no space for a screw 55 and a corresponding thread in the housing 5 is present on the entrance level of the pressure line 27.
- FIG. 4 shows a further variant of a valve insertion sleeve 60.
- the valve insertion sleeve 60 has a flange 62, which is fixed in the housing 5 in FIG. 4 b with 4 stiffeners 64.
- a corresponding positioning of inlet openings of the valve sleeve 60 and the housing 5 and the discharge bore 37 is possible.
- the flow control valve piston 15 and the corresponding spring 49 which presses the valve piston 15 against the valve sleeve 60, are additionally shown.
- a push-in pressure line for example, a screw-in pressure line could also be screwed into an internal thread 66 of the valve sleeve 60. Equally, however, the pressure line could be used as a push-in pressure line, such as shown as a pressure line 27 in Figure 1.
