Abstract

The invention relates to a water separator ( 10 ) for water contained in fuel or oil, having a water outlet ( 30 ) for the water separated from the fuel or oil and having a water discharge device ( 32 ), which comprises an inlet and an outlet opening ( 34, 36 ) for the water conveyed out of the water separator ( 10 ). According to the invention, the inlet opening ( 34 ) is eccentric to the longitudinal axis ( 20 ) of the water separator ( 10 ) and is arranged on the water separator at an axial distance from the water outlet ( 30 ), wherein the outlet opening ( 36 ) is arranged on the water separator coaxially to the longitudinal axis ( 20 ) of the water separator ( 10 ). The invention also relates to a separating system ( 100 ) having such a water separator ( 10 ).

First claim

1 . Water separator ( 10 ) for water contained in fuel or oil, comprising:
a water outlet ( 30 ) for the water separated from the fuel or oil; and a water discharge device ( 32 ) having an inlet and outlet opening ( 34 , 36 ) for the water conveyed out of the water separator ( 10 ),
wherein the inlet opening ( 34 ) is eccentric to the longitudinal axis ( 20 ) of the water separator ( 10 ) and is arranged on the water separator at an axial distance from the water outlet ( 30 ) and wherein the outlet opening ( 36 ) is arranged on the water separator coaxially to the longitudinal axis ( 20 ) of the water separator ( 10 ).

2 . Water separator according to claim 1 , characterized in that the inlet opening ( 34 ) and the outlet opening ( 36 ) of the water discharge device ( 32 ) are fluidically connected to each other by means of a first water discharge pipe ( 38 ), which is arranged inside the water separator ( 10 ) running in the direction of the longitudinal axis ( 20 ) of the water separator ( 10 ).

3 . Water separator according to claim 2 , characterized in that the first water discharge pipe ( 38 ) is arranged running coaxially to the longitudinal axis ( 20 ) of the separator ( 10 ), wherein the first water discharge pipe ( 38 ) forms the outlet opening ( 36 ).

4 . Water separator according to one of the preceding claims, characterized in that the water outlet ( 30 ) of the water separator is delimited at least in sections by a lower end plate ( 14 ) of the water separator ( 10 ).

5 . Water separator according to one of the preceding claims, characterized in that the water separator ( 10 ) has a support tube ( 12 ) and screen tube ( 26 ) arranged inside the support tube ( 12 ), which jointly delimit a water separating gap ( 28 ), wherein the water separating gap ( 28 ) is fluidically connected at one end to the water outlet ( 30 ) of the water separator ( 10 ).

6 . Water separator according to claim 5 , characterized in that a coalescing medium ( 24 ) and/or a filter medium ( 18 ) is/are arranged annularly around the support tube ( 12 ) and is/are supported on the support tube ( 12 ).

7 . Water separator according to claim 5 or 6 , characterized in that an ascension pipe ( 46 ) for the fluid is configured between the screen tube and the first water discharge pipe ( 38 ), which ascension pipe is fluidically connected to a fluid outlet ( 48 ) of the water separator ( 10 ).

8 . Water separator according to one of the preceding claims, characterized in that the inlet opening ( 34 ) of the water discharge device ( 32 ) is formed by a second water discharge pipe ( 40 ), which is arranged on the water separator offset in a direction radial to the longitudinal axis of the water separator ( 10 ), wherein the second water discharge pipe ( 40 ) and the first water discharge pipe ( 38 ) are fluidically connected to one another via a connection channel ( 42 ) that is arranged running in the radial direction.

9 . Water separator according to claim 8 , characterized in that the connection channel ( 42 ) is sealed axially in the direction of the inlet opening of the water discharge device ( 32 ) by a base plate ( 44 ), which is formed onto the second water discharge pipe ( 38 ).

10 . Water separator according to one of claims 5 to 9 , characterized in that the first water discharge pipe ( 38 ) and the screen tube ( 26 ) are configured together as one piece, preferably as an injection molded part.

11 . Water separator according to one of claims 5 to 10 , characterized in that the support tube ( 12 ), the first end plate ( 14 , 16 ) and a second end plate of the water separator are configured together as one piece, preferably as an injection molded part.

12 . Water separator according to one of the preceding claims, characterized in that the water separator ( 10 ) is provided with an end plate at both ends, wherein the two end plates each comprise a sealing element ( 52 ) for circumferential sealing contact of the water separator ( 10 ) on a separator housing ( 102 ) of a water separating system ( 100 ).

13 . Water separator according to claim 12 , characterized in that the sealing element ( 52 ) is arranged in an annular groove of the end plate ( 14 , 16 ), which annular groove is arranged on the inner circumferential side or the outer circumferential side.

14 . Water separating system ( 100 ) comprising a separator housing ( 102 ) having a water separator ( 10 ) arranged therein according to one of the preceding claims and having a water collection chamber ( 114 ), which is arranged beneath the water outlet ( 30 ) of the water separator ( 10 ) and into which the second water discharge pipe ( 40 ) of the water discharge device ( 32 ) extends with the inlet opening ( 34 ) thereof, wherein the separator housing ( 102 ) comprises a water discharge connecting piece ( 110 ), which is fluidically connected to the outlet opening ( 36 ) of the water discharge device ( 32 ) of the water separator ( 10 ).

15 . Water separating system ( 100 ) according to claim 11 , characterized in that the water collection chamber ( 114 ) comprises a recess ( 118 ), which is arranged laterally offset from the longitudinal axis ( 20 ) of the water separator ( 10 ) and into which the second water discharge pipe ( 40 ) of the water separator ( 10 ) extends.
