Embodiment Construction

[0028] FIG. 1 shows a pump device 1 as known from the prior art. For the sake of clarity, the pump insert itself is not shown and is provided for installation in section A. In a housing for receiving, for example a transmission, a receiving part 2 is accommodated, in which a suction channel 3 is provided for conveying the fluid, wherein the suction channel 3 is formed in a machined manner. The machined configuration of the suction channel 3 and thus the very neatly designed and machined inner surface I enable an optimization of the fluid flow into the pump chamber of the pump insert, thereby reducing or preventing the intake of air. An injector 5 is arranged in the suction channel 3 .

[0029] figure 2 The pump device 1 according to the invention is shown in a housing formed from components, which provides the receptacle 2 , wherein the pump device is also shown without a pump insert. The suction channel 3 is cast together in the receptacle 2 . The casting process of such ...

Abstract

The invention relates to a pump device (1) comprising a pump insert with no dedicated housing and a receiving part. Said pump insert is inserted into the receiving part (2). In the receiving part, a suction channel (3) is formed for the pump insert for suctioning a fluid and an inlay part (4) for optimizing the flow of fluid in the suction channel (3) is provided.

Description

technical field [0001] A pump device comprising a pump insert without its own housing, wherein the pump insert is inserted into a receptacle. Background technique [0002] A pump insert is known from DE 10 2011 055 020 A1, which does not have its own housing. Such pump inserts, also known as cartridge pumps, are inserted, for example, into the transmission housing. The insert is described, but the suction channel itself is not shown. [0003] A pump is known from DE 10 2013 25 622 A1 which has an insert in the inlet for sound insulation. [0004] From DE 43 34 228 A1 is known a hydraulic assembly made of cast parts, which has a filter insert in the suction area inside the pump. [0005] The intake channel for intake of the desired fluid for such a pump insert is usually machined in the transmission housing. However, machining is relatively cost-intensive to manufacture. A solution was thus found in which cost-effective production and at the same time an optimized fluid ...
