Abstract

A pressure filter device may include a filter housing having a filter housing pot and a filter housing cover connected to the filter housing pot in a pressure-tight manner. At least one filter element may be arranged in the filter housing. A vent line may be secured on the filter housing pot and connected to a crude-side gas collection region located directly beneath the filter housing cover to a tank.

Claims (34)

1 . A pressure filter device, in particular a hydraulic filter device, comprising:

a filter housing having a filter housing pot and a filter housing cover connected to the filter housing pot in a pressure-tight manner,

at least one filter element arranged in the filter housing,

a vent line secured on the filter housing pot and connecting a crude-side gas collection region located directly beneath the filter housing cover to a tank.

2 . A pressure filter device, comprising:

a filter housing having a filter housing pot and a filter housing cover connected to the filter housing pot in a pressure-tight manner,

at least one filter element arranged in the filter housing,

a vent line fixed to the filter element and being fed through an upper end disk of the filter element, the event line connecting, via a pure side of the filter element, a crude-side gas collection region located directly beneath the filter housing cover to a tank.

3 . The pressure filter device according to claim 1 ,

wherein the vent line, at least in the gas collection region, is configured as a flexible hose element capable of adapting to an inner contour of the filter housing cover.

4 . The pressure filter device according to claim 1 ,

wherein the vent line, at least in the gas collection region, is configured as a rigid pipe element capable of adapting to an inner contour of the filter housing cover.

5 . The pressure filter device according to claim 4 ,

wherein the pipe element has an articulated joint in a region of a transition between the filter housing cover and the filter housing pot.

6 . The pressure filter device according to claim 1 ,

wherein the vent line penetrates the filter housing pot.

7 . The pressure filter device according to claim 1 ,

further comprising a throttle arranged outside of the filter housing pot.

8 . The pressure filter device according to claim 1 ,

wherein the filter element includes on a lower end disk thereof. a hollow pin configured to engage a drain channel, and further wherein

the vent line is connected via the hollow pin in a communicating manner to the drain channel.

9 . The pressure filter device according to claim 8 ,

further comprising a plurality of protruding nozzles arranged on an upper end disk of the filter element configured to connect to the vent line.

10 . The pressure filter device according to claim 2 , wherein the vent line, at least in the gas collection region, is configured as a flexible hose element capable of adapting to an inner contour of the filter housing cover.

11 . The pressure filter device according to claim 2 , wherein the vent line, at least in the gas collection region, is configured as a rigid pipe element capable of adapting to an inner contour of the filter housing cover.

12 . The pressure filter device according to claim 11 , wherein the pipe element has an articulated joint in a region of a transition between the filter housing cover and the filter housing pot.

13 . The pressure filter device according to claim 2 , wherein the vent line penetrates the filter housing pot.

14 . The pressure filter device according to claim 2 , further comprising a throttle arranged outside of the filter housing pot.

15 . The pressure filter device according to claim 2 , wherein the filter element includes, on a lower end disk thereof, a hollow pin configured to engage a drain channel, and further wherein the vent line is connected via the hollow pin in a communicating manner to the drain channel.

16 . The pressure filter device according to claim 15 , further comprising a plurality of protruding nozzles arranged on the upper end disk of the filter element configured to connect to the vent line.

17 . The pressure filter device according to claim 3 , wherein the vent line, at least in the gas collection region, is configured as a rigid pipe element capable of adapting to an inner contour of the filter housing cover.

18 . The pressure filter device according to claim 3 , wherein the vent line penetrates the filter housing pot.

19 . The pressure filter device according to claim 3 , further comprising a throttle arranged outside of the filter housing pot.

20 . The pressure filter device according to claim 3 , wherein the filter element includes, on a lower end disk thereof, a hollow pin configured to engage a drain channel opposite the pure side, and further wherein the vent line is connected via the hollow pin in a communicating manner to the drain channel.
