Water filter abstract
A water filter for radiators is provided which is characterized
by the fact that it is fitted with a thick internal cylindrical
mesh inserted into another cylindrical mesh similar to the foregoing
but with a finer mesh. Both meshes are fixed by supports placed
by pressure between both means and a coupling flange.
Water filter claims
What is claimed is:
1. An automobile radiator water filter comprising:
a generally cup-shaped external filter screen having a generally
cylindrical sidewall and a generally hemispherical base wall and
having a relatively fine mesh width and an open end;
a generally cup-shaped internal filter screen having a generally
cylindrical sidewall and a generally hemispherical base wall and
having a relatively larger mesh width than that of said external
filter screen, said internal filter being disposed within said external
filter and having an open end;
support means disposed between said screens for maintaining them
in a fixed, spaced-apart relationship to one another, said support
means including side supports disposed between the sidewalls of
said screens and a base support disposed between the base walls
of said screens; and
a flat, annular coupling flange disposed across and joining together
the open ends of said screens, said flange having an annular lip
projecting laterally beyond the open end of said external screen
which serves to mount said filter in a radiator inlet.
Water filter description
The present invention relates to a water filter for radiators,
especially automobile radiators.
More particularly, the present invention provides a water filter
for radiators which includes a generally cylindrical external filter
screen having a relatively fine mesh width and an open end, and
a generally cylindrical internal filter screen having a relatively
larger mesh width than that of the external filter screen. The internal
filter is disposed within the external filter and it too has an
open end. Support means are disposed between the filters for maintaining
them in a fixed, spaced-apart relationship to one another, and a
coupling flange is disposed across and joins together the open ends
of the screens.
The technical advantages achieved by the above-mentioned filter
are the result of observations, tests and experiments carried out
with the fundamental object to find a truly integral technical solution
for certain problems and difficulties observed in radiators and
cooling systems caused by the accumulation of incrustations, rust,
etc., and to the difficulties encountered to eliminate the same
or at least prevent their interference in the correct and normal
operation of a water-cooled engine.
The filter of the invention is particularly applicable to the water
fed cooling systems for the different types of engines that are
supplied with a water pump, and which have the capacity to circulate
the water from the radiator through a filter for its adequate purification.
Other objects and features of the present invention will become
apparent from the following detailed description, considered in
connection with the accompanying drawing, which discloses a single
embodiment of the invention. It is to be understood, however, that
the drawing is designed for the purpose of illustration only, and
not as a definition of the limits of the invention.
In the drawing, wherein similar reference characters denote similar
elements throughout the several views:
FIG. 1 is a schematically illustrated perspective view of a filter
embodying the present invention, as seen from the top end or inlet
FIG. 2 is a longitudinal cross-sectional view of the filter shown
in FIG. 1 .
Referring now in detail to the drawing, a water filter for radiators
embodying the present invention is illustrated which is composed
of a cup-shaped, mesh or fine filtering external screen 1 internally
of which is disposed another mesh or filtering screen 2 of similar
cylindrical shape but having a larger mesh width than the mesh mentioned
above. Fine filtering screen 1 is fixed to filtering screen 2 by
means of side pressure supports 3 and one support 4 on the base
of the filter for a correct adjustment and easy fixing. Furthermore,
on the top portion or inlet opening of screens 1 and 2 flange 5
is attached which serves as a support in the radiator inlet.
In FIG. 1 of the attached drawing, the complete filter may be observed,
correctly designed for placement in the circulation opening of the
radiator. The filter is held in place by flange 5 so as to establish
the stability of the filter with the water circulation passage.
FIG. 2 illustrates a longitudinal sectional view of the filtering
elements showing the correct disposition for the natural water passage
and thus the retention of foreign matter. In particular, the water
to be filtered is filtered first by the thick network or wide mesh
of screen 2 which is separated from the next filter 1 by supports
3 and 4. The partially filtered water then begins a new passage
and further purification through another mesh of screen 1 of a finer
network or mesh than that of screen 2.
With reference to its practical fitting, and in accordance with
that illustrated in FIGS. 1 and 2 of the attached drawing, the access
opening of the filter is inserted in the inlet of the radiator and
is fixed therein by flange 5; this being the ideal location for
the retention of foreign matter in the water, as it is the natural
opening to the circulation circuit of the engine cooling system
liquid that is driven by a complementary pump. As noted above, the
water initially passes through the first filter or mesh 2 which
retains most of the foreign matter in the water, as the same is
of a very fine network. Subsequently, the water passes through another
mesh or screen 1 with a still finer mesh, where even the most minute
foreign matter is retained which was not retained by the preceding
screen. In this way a perfect operation of the engine cooling system
is obtained, and simultaneously the damage caused by incrustations,
rust, etc., and the consequent overheating of the engine is avoided.
This water filter as may be observed is easily fitted, is simple
and of an easy assembly, with materials that offer great efficiency
and low manufacturing costs.
Besides the foregoing, it is doubtless that in putting the present
invention into practice, some modifications may be introduced as
regards certain details, without this involving a departure from
the basic principles which are clearly specified in the following
Thus, while only a single embodiment of the present invention has
been shown and described, it will be obvious that many modifications
and changes may be made thereunto, without departing from the spirit
and scope of the invention.
