Definitions
- the invention relates to a device for promoting Hydraulic oil, lubricating oil or the like according to that in the preamble of claim 1 defined in more detail.
- Such a device is known from practice and for example designed as a drive unit of a hydraulic system.
- the device can be used as a small hydraulic unit be carried out, which essentially from a reservoir for hydraulic oil, a pump, for example a gear pump, a so-called valve block, to which the pump is attached and which one Consumer connection for connecting a hydraulic consumer, such as a hydraulic cylinder or hydraulic motor and an electric motor to drive the pump consists.
- a hydraulic consumer such as a hydraulic cylinder or hydraulic motor and an electric motor to drive the pump consists.
- the connection of the hydraulic consumer can if necessary, take place via a controller, which is essentially consists of valves and their interconnection.
- a controller which is essentially consists of valves and their interconnection.
- Such a device is, for example, from the document EP 1 008 750 known.
- valve block is in the known devices for Promotion of fluids of the type mentioned in the introduction in usually made of die-cast aluminum or forged aluminum.
- valve blocks A disadvantage of such known valve blocks is that in manufacturing there is a need to use the same to machine it with adjacent components to be able to connect. However, this is complex and costly, which has a corresponding negative impact on the cost of Precipitation device.
- valve block for pumping hydraulic oil, Lubricating oil or the like with the features according to the preamble of claim 1, in which the Valve block at least partially a molded plastic part in which at least one further component of the device is encapsulated by plastic, in contrast the advantage that the at least one other component of the Device in a plastic injection mold in a simple way with the valve block.
- valve block can be integrated in one Area mechanically and / or hydraulically less loaded Areas have recesses.
- polluted areas can also have metallic reinforcements in the valve block be encapsulated by plastic, for example can be provided with ribs.
- valve block and adjacent to or integrated into this Components form a structural unit, which in the device can be easily assembled.
- the pump flange is the at least one further component of the device.
- the pump flange is then overmolded with plastic and forms one with the valve block Unit.
- valve block it is, for example, mechanical or hydraulic highly loaded suction elements.
- Components of this type can, for example, a connector for a consumer or a threaded sleeve, for example for Engagement of a fastening screw of a drive motor for the pump.
- a metallic connector for a consumer this can be done in one also metallic injected into the valve block Guide part to be arranged.
- the valve block is preferably also in the area of Anchoring of the plastic storage container.
- the in plastic present in this area creates the possibility the valve block in a cost-effective manner by means of a To connect the bayonet lock to the storage container.
- an aluminum wall in this area such as they can be found in the devices according to the prior art would be such a type of connection with a bayonet lock in common applications, such as with a small hydraulic unit, with too high manufacturing costs connected.
- FIGS. 1 and 2 show a small hydraulic unit 1 shown, the essential components of a pressure medium reservoir 2, one for example as a gear pump trained hydraulic pump 3, a so-called Valve block 4 and an electric motor 5 for driving the Has hydraulic pump 3.
- a pressure medium reservoir 2 one for example as a gear pump trained hydraulic pump 3, a so-called Valve block 4 and an electric motor 5 for driving the Has hydraulic pump 3.
- valve block 4 which in the present case is a plastic injection molded part is formed and, if necessary, metallic reinforcements may include controls for Control of the hydraulic small unit 1 and is used for attachment other components of the small hydraulic unit 1.
- the hydraulic pump 3 essentially comprises three housing parts 6, 7 and 8, wherein the housing part 8 is a pump flange represents for fastening the pump to the valve block 4.
- valve block 4 is in the range of one Recess 12 from a likewise designed as an insert so-called high-pressure insert 11, which one made of a metallic material, for example aluminum, manufactured connector for a not shown here hydraulic consumers, such as a hydraulic cylinder, is.
- high-pressure insert 11 one made of a metallic material, for example aluminum, manufactured connector for a not shown here hydraulic consumers, such as a hydraulic cylinder, is.
- the high-pressure insert 11 has a small hydraulic unit inside 1 lying end 18, which in the to the valve block 4 adjacent pump flange 8 of the hydraulic pump 3 protrudes. In this area is between high pressure use 11 and the pump flange 8 are designed as an O-ring Seal 13 arranged.
- the plate-like pump flange 8, the high pressure insert 11 and the threaded inserts 10 are in the Valve block 4 injected or overmolded with plastic. These components are thus firmly connected to the valve block and form a structural unit with the latter.
- the valve block 4 is also in the area of the anchorage of the pressure medium reservoir made of plastic 2 made of plastic.
- the anchorage of the pressure fluid reservoir 2 on the valve block 4 is a bayonet lock 14 executed.
- For sealing the storage container 2 compared to the environment is in the area of the bayonet catch 14 additionally one designed as an O-ring Seal 15 arranged.
