Definitions
- the invention relates to a piston pump, in particular for brake pressure generation in a hydraulic vehicle brake system according to the generic features of claim 1.
- piston pumps are known for example from DE 101 12 618 Al. These known piston pumps have a pump housing with a receiving bore formed thereon. In this receiving bore a bushing of the piston pump is used. The bushing carries a piston which can be driven by an eccentric to a reciprocating stroke movement and which limits a variable in volume pressure chamber. A pressure medium flow through the piston pump is controlled by valves. The pumped pressure medium flows via a discharge channel of the pump to a pressure medium channel in the pump housing.
- FIGS. 5, 8 and 9 show piston pumps, in which one of the valves for controlling the flow of pressure medium by the piston pump is arranged detached from the piston in an installation space of a valve cover.
- the valve cover closes the receiving bore of the pump housing pressure-tight against the environment.
- This solution has the advantage over the other variants shown that the valve does not follow the piston movement and that thereby the acceleration or deceleration occurring on the piston does not influence the opening or closing behavior of the valve.
- a pressure medium channel of the pump housing opens in the solutions according to Figures 5, 8 and 9 beyond the inner end of the valve cover into the receiving bore. However, this results in a relatively large axial distance from this pressure medium channel to an outside of the pump housing. This large distance has a negative effect on the volume of the pump housing.
- a piston pump according to the features of claim 1 has the advantage that the distance of the pump housing side pressure fluid channel is reduced from an outside of this pump housing.
- the pressure medium channel is thus closer to one of the outer sides of the pump housing and thereby enables better utilization of the installation space of the pump housing, for example for the arrangement of further, not shown, pressure medium channels or the like. Overall, this can be realized a compact designed pump housing. Construction volume, material requirements and weight are an essential competition criterion, especially in vehicle construction due to the limited installation conditions.
- first and second channel sections of the outflow channel can advantageously be arranged against the background of a maximization of the available cross-sectional area. As large as possible cross-sectional areas are to be strived for, so that no throttling effect emanates from the discharge channel.
- the advantages offered by claim 5 also offer ring grooves. drawing
- FIG. 1 shows an inventively designed piston pump in longitudinal section.
- FIG. 2 shows a valve cover of the piston pump in the top view
- Figure 3 shows this valve cover for clarity again in a three-dimensional view.
- the piston pump 10 shown in FIG. 1 is arranged in a hydraulic unit of an electronically slip-controllable vehicle brake system and serves to regulate the brake pressure in at least one wheel brake, which is connected to this hydraulic unit via brake lines.
- the hydraulic unit comprises a pump housing 12 and an e-lektronisches control unit attached thereto, not shown.
- the pump housing 12 is provided inter alia with a receiving bore 14, in which a piston pump is installed.
- This receiving bore 14 is offset several times in its inner diameter from outside to inside and opens to an outer side 16 of the pump housing 12 out.
- In the receiving bore 14 open transversely extending pressure medium channels 18, 20 a.
- a first pressure medium channel 18 facing away from the outer side 16 forms an inlet and supplies the piston pump 10 with pressure medium, while a second pressure medium channel 20 facing the outer side 16 of the hydraulic unit acts as a drain and leads pressure medium away from the piston pump 10 under elevated pressure.
- a bush 22 of the piston pump 10 is set.
- This bushing 22 is cup-shaped and has a ner passage hole provided, flat Laufbuchenboden 24 and a one-piece associated hollow cylindrical journal shaft 26.
- the bush bottom 24 faces the outside 16 of the pump housing 12.
- a sleeve-shaped filter element 28 is attached to the bushing shaft 26. The latter extends beyond the end of the bushing 22, whereby the section of the filter element 28 projecting beyond the bushing 22 is retracted in the outer and inner diameters and thereby partially covers an opening cross-section of the bushing shaft 26.
- the filter element 28 simultaneously acts as an axial piston for a piston 30 movably received in the bushing
- the piston 30 is constructed from two piston parts 32, 34.
- the first piston member 32 protrudes from the filter element 28 and forms the drive side of the piston 30. It is cylindrical and provided at its end facing the bushing with a centrally arranged, blind hole-shaped recess. In this recess, the second, sleeve-shaped executed piston part 34 projects in sections.
- On the outer circumference of the second piston part 34 a circumferential sealing / guiding region 36 is formed, which bears against the inner side of the bush 22.
- This sealing / guiding region 36 guides the piston 30 and at the same time seals a pressure chamber 38 of the piston pump 10 located between the piston 30 and the bush bottom 24. As a result of the pressure prevailing in the pressure chamber 38, the sealing / guiding region 36 is pressed against the inside of the bushing 22 in a reinforced manner.
- a return spring 40 is housed, which is supported at one end on the bushing bottom 24 and the other end of the piston 30 in the direction of a piston movement causing the drive element (not shown) acted upon.
- the piston-side end of the return spring 40 is indirectly via a cup-shaped inlet valve housing 42 of an inlet valve 44 on the piston
- the inlet valve housing 42 is peripherally provided with openings and receives in its interior an inlet valve spring 46. This presses an inlet valve member 48, which is designed in the form of a valve plate in the embodiment, against an inlet valve seat 50. The latter is formed at the open end of the second piston part 34.
- a valve cover 52 seals the receiving bore 14 from the environment. For this purpose, this valve cover 52 is pressed into the receiving bore 14 and is held in a form-fitting manner by caulking of the material of the pump housing.
- the valve cover 52 has at its inner end face a circumferential annular shoulder 54 and an opposite the annular shoulder 54 axially projecting collar 56 with a narrow cross-section.
- the bushing 22 and the annular shoulder 54 are matched in their diameters, whereby the collar 56 of the valve cover 52 surrounds the bushing 22 on the outer circumference.
- the bushing 22 is supported with its bush bottom 24 on the annular shoulder 54 of the valve cover 52 from.
- a centrally formed on the valve cover 52 flat countersinking 58 limits the inner diameter of the annular shoulder 54 and forms a cavity between the sleeve 22 and the valve cover 52.
- This flat countersink 58 merges into a blind hole-like central recess 60 of the valve cover 52.
- an outlet valve spring 62 is installed, which acts on an outlet valve body 64.
- exhaust valve body 64 is a ball which cooperates with a formed on the bush bottom 24 exhaust valve seat 66.
- Figure 2 shows in a plan view, lying in the interior of the receiving bore
- Recess 72 hydraulically contacted.
- This first recess 72 extends parallel to the longitudinal axis of the valve cover 52 over the entire length of the collar 56 and forms a first channel section 74 of a discharge channel of the piston pump 10.
- a plurality of such first recesses 72 are formed.
- annular groove 76 likewise present on the annular shoulder 54, establishes a hydraulic connection between the radially extending groove 70 and a second first recess 72 on the inside of the collar 56.
- this further recess 72 of the first recess 72 is opposite.
- second recesses 78 are formed on the outside and create second channel portions 80 of the outflow channel of the piston pump 10.
- the outside, second recesses 78 have a greater axial length than the inside first
- Recesses 72 Furthermore, the outside and the inside recesses 72, 78 are arranged offset in the circumferential direction of the collar 56 to each other gap, so that the collar 56 viewed from above has a corrugated contour.
- a contour can be produced, for example, by machining the valve cover 52 or at lower cost by means of forming technology.
- the outer and inner recesses 72, 78 open at the end of the valve cover 52 to the receiving bore 14 of the pump housing 12 out and are thereby hydraulically connected to the outflow channel of the piston pump.
- a pressure medium channel 20 is present in the pump housing 12, which discharges the pressure medium conveyed by the piston pump 10.
- This pressure medium channel 20 extends transversely to the receiving bore 14 and opens into this.
- the mouth of the pressure medium channel 20 is due to the outside recesses 78 on the collar 56 at the level of the valve cover
- FIG. 3 again shows the already described valve cover 52 in a perspective view and therefore does not require any additional explanation.
- the introduced reference numerals have been retained for FIG.
- the piston 30 of the piston pump 10 is from a drive element, not shown, for example, an eccentric or a cam, to a back and driven reciprocating stroke movement.
- a drive element not shown, for example, an eccentric or a cam
- the volume of the pressure chamber 38 bounded by the bushing 22 and the piston 30 changes. If the piston 30 is moved to the left by the drive element against the force of the return spring 40 in FIG. 1, the volume of the pressure chamber 38 decreases and is contained therein Pressure medium is a pressure increase. Along with the force of the inlet valve spring 46, this pressure increase causes the inlet valve member 48 to be pressed against and seal the inlet valve seat 50.
- the exhaust valve member 64 lifts off the exhaust valve seat 66 and the exhaust valve opens.
- the pressure medium of the pressure chamber 38 then flows into the gap formed by the countersink 58 in the valve cover 52 between the bush 22 and the valve cover 52 and from there via the radially extending groove 70 of the annular shoulder 54 to the first
- the 180 ° deflection of the pressure medium flow in the receiving bores 14 has a damping effect on pressure pulsations, which can occur due to the cyclical drive of a piston pump.
- Dead center reverses its direction of movement and the volume of the pressure chamber 38 gradually increases again. Accordingly, now there is a negative pressure in the pressure chamber 38 a. This, together with the exhaust valve spring 62, causes the exhaust valve member 64 to be pressed against the exhaust valve seat 66 and close the exhaust valve. At the same time, the inlet valve member 48 lifts off from the inlet valve seat 50 counter to the force of the inlet valve spring 46, and new pressure medium flows via the sleeve-shaped second piston part 34 into the pressure chamber 38 of the piston pump 10. Both processes are repeated cyclically in response to the actuation of the piston 30 by the drive element.
- changes or refinements of the described embodiment are conceivable without departing from the spirit of the invention.
