Embodiment

Accompanying drawing relates to the utility model embodiment relevant to filter assemblies 1 for diesel oil, but other embodiments of the present utility model can relate to the filter assemblies of the fuel for filtering other types.

Fig. 1 has shown filter assemblies 1, and this filter assemblies 1 comprises shell 2, and this shell 2 is beaker shape, is preferably sealed by lid 3, is positioned at lid 3 for inlet ducts 4 and the delivery channel 5 of fuel.

The annular filter wall 6 with symmetrical principal axis A is contained in this shell 2, and this filter wall 6 is provided with lower plate 60 and upper plate 61.This plate 61 is provided with hollow center pillar (spur) 62, for inserting another pillar 8 that is derived from this lid 3; Described lower plate 60 is positioned on the supporting member 7 that is contained in described outer casing bottom.

The internal capacity of described shell 2 is roughly divided into two different chambers 9 and 10 by described filter wall 6, and wherein this first Room 9 is set to be communicated with the inlet ducts 4 of fuel to be filtered, and the second Room 10 is set to be communicated with the delivery channel 5 of the fuel filtering.

This supporting member 7 have 3 lean on pin, be respectively 11,12 and 13, they with respect to described symmetrical principal axis A angularly each other equidistantly away from.Described dependence pin 11,12 and 13 is positioned near diapire 20 places of the described shell cylindrical wall 21 of described shell 2.

Particularly, in the embodiment shown, described dependence pin is set to contact with the cylindrical wall 21 of described shell 2.

Support device is connected to this dependence pin 11, and this dependence pin 11 is for supporting fixture, for example device 14 as shown in phantom in Figure 4, and this device 14 is for detection of the water level of the water of collecting in these shell 2 bottoms.This support device comprises tapped hole 15, and the corresponding helical thread portion of this device 14 is screwed into this tapped hole 15.

Significantly, the cylindrical wall 21 of this shell 2 has corresponding hole 150, and this hole 150 makes described device 14 be screwed into hermetically in described tapped hole 15 from this housing exterior.

In embodiment as shown in Figures 1 to 4, the longitudinal axis of this tapped hole 15 is set in use, or in the time that this dependence pin 11,12 and 13 relies on this diapire 20, roughly vertical with the symmetrical principal axis A of this filter wall 6.

Or as shown in Figure 5, the longitudinal axis in this hole 15 can differently tilt with respect to the symmetrical principal axis A of this filter wall, even can be basically parallel to this symmetry main shaft.In interchangeable embodiment as shown in Figure 5, the rear wall of this shell 2 and cylinder side wall 21 link together, to define the bottom of circular of this shell self.

These three dependence pin 11,12,13 are connected to each other by vertical wall 16, and this vertical wall 16 has defined Delta Region roughly.In the embodiment shown, this wall 16 is at intermediate support cylinder body 17, and this cylinder body 17 is connected to this wall by a series of stiffening rib 18.Described cylinder body 17 is provided with central hole 19, and the symmetrical principal axis A of the axis of this central hole 19 and this filter wall 16 is overlapping.

This central hole 19 has internal thread, and for sealing fastening another fixture, the discharge tap 22(of for example known type is shown in Fig. 1 and 5), for the water that separates from fuel and collect from the bottom of this shell 2.In this case, naturally, the diapire 20 of this shell is provided with central hole 19, thereby operator can be screwed onto this tap 22 in this central hole from the outside of this shell 2 hermetically.

How to use and for example set in advance, for (being connected fixture from can clearly knowing description of the present utility model, water level and/or temperature transducer and/or heating equipment or similar device) the supporting member 7 of device there is advantage, because this makes supporting member become possibility for the various filter assemblies with different shells, reduce cost of production.

Another advantage is, according to the application target of this filter assemblies, can use whole or in part the connection set of this fixture.

For this fixture is installed, only need on this shell, set in advance the hole of enough numbers, these holes are with corresponding for the device that connects this supporting member 7.

The utility model is not limited to above-described embodiment, not departing under the prerequisite of scope defined by the following claims, can make any amendment or improvement.
