Description
- This patent application is a United States nation phase patent application based on PCT/DE2022/200069 filed on Apr. 7, 2022, which claims the benefit of German Patent Application No. 10 2021 204 072.1 filed on Apr. 23, 2021, the entire disclosures of each of which are hereby incorporated herein by reference.
- The invention relates to a cartridge pump. Especially in the automotive sector, cartridge pumps are provided, for example, as oil pumps which are installed in suitable housings, by means of which the components of the pump, for example, are centered.
- Such a cartridge pump is known from EP 3081741 A2.
- As a subject matter of the prior public use, there is also known a cartridge pump, in which a pin present and extending through numerous components of the pump is used to mount a circlip that holds a bushing or a Belleville spring so that the components of the pump are connected in a resilient manner and are not detachable. This makes the cartridge pump transportable and after installation, the corresponding components of the pump can rotate in a suitable manner. Especially when using a spring element of elastomer, there is, however, the problem that the spring tension decreases during the service life. Furthermore, the aim is always to configure such a cartridge pump particularly simple.
- Against this background, the invention is based on the object of creating a cartridge pump that can be produced in a cost-effective manner and can be transported and mounted safely.
- Accordingly, at least one component of the cartridge pump is held in a non-resilient and non-detachable manner, in particular in a force-fitting manner, without a screw connection. Consequently, transportability is ensured, and any spring element and screw connection can be dispensed with at the same time. This enables the construction to be simplified, and the above-described problems when using an elastomer spring element can be avoided.
- Moreover, no fixation has to be removed during installation, thus making installation easier as well. The same is equally true for a possible disassembly since the components of the cartridge pump are permanently held together, and the cartridge pump can therefore be removed in a simple manner. Finally, the securing measures, for example in the form of the bushings described below or one or more washers, are very limited locally, for example to the immediate vicinity of the pins that are present anyway. It can thus be avoided in an advantageous manner that areas of the pump that are to be kept open, such as inlets or outlets, are covered as a result of securing measures.
- Preferred further developments of the cartridge pump according to the invention are described in the further claims.
- The described holding of at least one component can be realized particularly easily by pressing a bushing or washer onto at least one pin that is typically always present and extends through numerous components of the pump. Such a configuration is also possible in an advantageous manner with a comparatively thin pin, for example with a diameter of about 3 mm, and is in particular more cost-effective than, for example, a screw connection. Such a bushing may advantageously have a widened head that is located at the free end of the pin to facilitate disassembly of the bushing. The axial extent of such a bushing or washer is preferably many times smaller than the axial extent of the pin.
- Preferably, the pin is substantially cylindrical with a round and/or circular cross-section. The section of the pin onto which the bushing or washer is pressed preferably does not have grooves, notches or other discontinuities. In other words, preferably in the area of the pressed-on bushing or washer, the pin does not deviate from the substantially cylindrical shape. However, the foregoing does not preclude the pin from having a groove or notch in which a circlip can be fitted.
- Preferably, the pin extends through the at least one held component such that the pin protrudes with at least one (axial) end, more preferably with both (axial) ends, in the axial direction at least over a section of the at least one held component (preferably over the section of the at least one held component through which the pin extends).
- Although the pump components do not have to be held completely immobile, for example along the mentioned pin, it is advantageous if the pump components are held immobile, i.e. without clearance. By this, damage due to movements during transport can, for example, be avoided.
- In principle, the described measures, for example a pressed-on bushing, can be provided on both ends of a pin to hold the pump components in a non-resilient and non-detachable manner. However, it is conceivable to provide a circlip on one end of the pin, which in a known manner can have an opening so that the circlip can be mounted on a groove formed in the pin. Alternatively, however, the pin may have a widened cross-section at one end.
- Due to the bushings, washers or combination of bushing, washer and/or circlip being mounted on the ends of the pin, the at least one component or the pump components can be held on the pin in a form-fitting manner. However, the at least one component or the pump components can also be held on the pin in a force-fitting manner by means of the bushings, washers or the combination of bushing, washer and/or circlip. The force fit is formed in particular between the bushings, washers or the combination of bushing, washer and/or circlip and the at least one component. As an alternative to bushings, washers and circlips, other means or combinations of different means are also conceivable which are suitable to form the form fit and/or force fit described above.
- The above-mentioned means moreover also allow the force fit to be formed between the individually-held pump components. In particular, it is also possible to press the pump components together with a predetermined force. This prevents twisting of the at least one component or of the pump components with respect to the pin as well as twisting of the individual pump components with respect to each other.
- The invention exhibits its advantages to a particular extent when the component held in the manner described above is an inlet section, a pump section, a control plate, a pump holder and/or a motor housing. In particular, several or all of the mentioned components can be held in the manner described above, especially by one or more pins and bushings or washers. In a single pump, a single pump section or a single pump holder may be provided. For example, a vane pump, gerotor or other type of positive displacement pump may be held as the pump section. In a multiple pump, multiple pump sections and/or multiple pump holders may be held, for example, one gerotor, vane pump or other type of positive displacement pump in each case. The inlet section mentioned above may be essentially a plate with the pump inlet.
- A particularly efficient configuration is achieved in that at least one pin extends through the relevant individual parts of the cartridge pump, and the individual parts of the cartridge pump are thus held in position.
- Moreover, for an efficient use of the available installation space and for a simple assembly process, advantages are achieved if at least one bushing or washer is located in a motor housing.
- It is particularly advantageous for mountability if at least one bushing or washer is located on an outer side of the cartridge pump.
- Embodiment examples of the invention shown in the drawings will be described in more detail below. The drawings show the following:
-
FIG. 1 a partial sectional view of a cartridge pump according to the invention; -
FIG. 2 one detail of the cartridge pump shown inFIG. 1 ; -
FIG. 3 an alternative to the detail shown inFIG. 2 ; and -
FIG. 4 a partial sectional view of a second embodiment. - As can be seen in
FIG. 1 , in the case shown, thecartridge pump 10 according to the invention has twopins 12 extending through various components of the pump to hold it together. In the case shown, abushing 14 is pressed onto the outer end, i.e. lower end inFIG. 1 , of therespective pin 12, and a washer is pressed onto the upper end according toFIG. 1 , in order to hold the described components without the need for a spring element and in a non-detachable manner, in particular without clearance in the case shown. -
FIG. 2 shows thebushing 14 on one end in detail together with surrounding components of thecartridge pump 10. Thepin 12 may be dimensioned in particular such that it does not protrude or protrudes only slightly on at least one end beyond therespective bushing 14. - It is additionally apparent from
FIG. 3 that thebushing 14 may have a widenedhead 16 on the free end of thepin 12 to facilitate handling during assembly. - As the second embodiment,
FIG. 4 shows a multiple pump which, according to the representation in the figure from bottom to top and in the manner according to the invention, holds together aninlet section 18, apump section 20 of a first pump, acontrol plate 22, apump holder 24 of a second pump, and amotor housing 26. According toFIG. 1 , awasher 14 is shown inside themotor housing 26, and the bushing according toFIG. 3 is shown outside the pump insert, constituting the cartridge pump. However, it goes without saying that thebushing 14 shown inFIG. 1 below may also be provided here without a widenedhead 16 or a washer. Similarly, in both embodiments, instead of the bushings orwashers 14 shown, the other mentioned securing means may be provided in the corresponding places with or without an additional circlip. - Against the background of
FIG. 4 , it should be mentioned that the components shown inFIG. 1 between themotor housing 26, according toFIG. 1 above, and thelower bushings 14 may be, in this order from top to bottom, a control plate, a pump section, and an inlet section.
