Definitions
- the invention relates to a high-pressure cleaning device a pump and one driving it in a motor housing arranged electric motor, in the case of the motor driven moving parts of the pump in an oil filled Housing are arranged, which is between the engine and pump is located, the pump below the electric motor is arranged and the oil-filled housing at its highest point a connection opening to one Has oil reservoir that is above the highest Extends the place of the oil-filled housing.
- a pump arrangement is known from US-A-4597720, where the engine case itself has an oil reservoir forms, which is oil-filled to a certain level is. With such an arrangement, it is difficult to adequate circulation in the oil-filled cavity and to achieve sufficient cooling.
- a generic high-pressure cleaning device to design so that also at a vertical arrangement ensures that all Sufficient parts in the oil-filled housing come into contact with the oil filling.
- This task is done with a high pressure washer of the type described in the introduction solved that the oil reservoir outside the motor housing arranged and over two at a distance from each other overlapping openings with the oil-filled Housing is connected and that the two openings in Areas of oil-filled casing enter from each other are separated, but via a storage roller bearing serving the motor shaft connected are.
- This Circulation flow helps to prevent unintended Air pockets, for example in the Filling can occur, be removed immediately, on the other hand, you get an essential one improved mixing of the entire oil filling, see above that once the cooling of the overall arrangement significantly is improved and secondly the abrasion in the Oil filling is distributed much more evenly. Thereby it becomes possible with a certain oil filling to work over a longer period of time.
- the movement the rolling element in the rolling bearing also leads to a Oil is pumped through the roller bearing That is, the rolling bearing acts as a pump that fills the oil transported from one area to another and thereby a constant circulation of the oil from one area guaranteed in the others. Over the openings, with which the two areas each with the oil reservoir connected, this cycle is closed and only in the oil reservoir, so that the oil supply in the oil reservoir is active in the circuit is involved.
- the pumping effect through the roller bearing is further improved, if in that connected to the lower opening Swashplate drive area of the oil-filled housing is arranged for the pump.
- a swash plate drive promotes through the movement of the swashplate the oil filling in the axial direction greater depth of the oil-filled housing towards the roller bearing, that is, the swash plate drive and the rolling bearing together form the active pump unit for the oil filling of the housing filled with oil.
- This effect is particularly favorable when the swash plate drive right next to the roller bearing of the motor shaft is arranged.
- the motor pump unit 1 of the present invention comprises an electric motor arranged in a housing 2 3 with a vertically arranged motor shaft 4, which on the upper end of the housing 2 is supported by a ball bearing 5 is.
- the motor shaft follows in this area from the top of the housing 2 and carries a fan wheel there 6th
- the housing 2 At the opposite end is the housing 2 a downwardly open, pot-shaped housing 7, in which enters the motor shaft 4 sealed. In the entrance area the motor shaft 4 is sealed through a ring seal 8 surrounding it.
- a ball bearing 10 is arranged, which supports the motor shaft 4. This transverse wall 9 divided thus the interior of the housing 2 in one upper area 11 and into a lower area 12.
- the motor shaft 4 ends in the lower region 12 and carries there a swashplate 13 connected to it in a rotationally fixed manner, against which pistons 15 are pressed by springs 14, which are part of a pump 16.
- This pump 16 includes one Pump head 17 with pump chambers 18 into which the pistons 15 Immerse sealed.
- the pumping chambers 18 are over a suction valve 19 with a suction line 20 and over Pressure valve 21 connected to a pressure line 22.
- the pump head 17 is sealed to the open end of the housing 7 placed so that through the housing 7th and the pump head 17 has a closed volume, essentially the moving parts of the motor pump unit picks up, so the ball bearing 10, the Swash plate 13 and oscillating from the swash plate driven piston loaded by springs 14 15th
- Both the upper area 11 and the lower area 12 are available via a lateral inlet opening 23 the interior of an outside of the housing 2 Oil reservoir 24 in connection, which extends up extends above the upper area 11 and so is far filled with an oil filling 25 that the upper Level 26 of the oil filling in the oil reservoir 24 above the upper edge of the upper region 11.
