Improvements in Fluid Pressure and like Valves.
I, BENEDICT HÜBBE, of 61, Wollankstrasse, Pankow, Berlin, in the Empire
of Germany, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to valves consisting of superposed rings having annular
openings, between which rings elastic flanged washers are so arranged that the
flanges form annular lips projecting into the annular openings in the rings and
admitting of the passage of the fluid through the said lips and rings in one
direction only. The essential feature of the invention consists in firmly secur-
ing the elastic annular lips between the annular supports or superposed rings
arranged one above the other, the said rings and elastic lips being preferably
held together by means of a bolt and nut.
By means of this arrangement the sum of the cross-sections of the passage-
openings, formed by the valve rings is larger than in those valves, in which the
elastic annular lips are located in one and the same plane. Moreover the elastic
annular lips admit of being subjected to a higher pressure. The elastic washers
are provided with upwardly directed flanges.
In one constructional form of the improved valve each of the superposed
annular valve rings is formed by one rigid ring and one elastic washer. The
elastic washers are held in position at the lower rims or edges between the
metal rings. The rings are, however, so constructed, as to serve as abutments
for the upright rims or flanges of the adjacent elastic washers. The method of
operation is as follows:-the liquid, traversing the annular openings in one
direction, forces open the elastic lips of the flanged washers.
This form of valve has the advantage, that the valve is rendered applicable
for higher pressures, seeing that the ring, serving as an abutment, forms, as it
were, a rigid stop which prevents the upright lip of the elastic washer from being
forced down. It is preferable, that the supporting rings, constructed in the
form of abutments, should be so arranged, as to outwardly surround the elastic
washers, thus, on the one hand, the elastic washers are protected from injury
through mechanical action, while, on the other hand, the elastic lips are pre-
vented from opening too far. The uppermost ring, according to this construc-
tion, is preferably made in the shape of a hollow body, serving as an air chamber.
All the rings are, likewise in this case, held together by a bolt and nut.
Another constructional form of the valve differs from that above described,
inasmuch as the rings are not arranged in the form of steps or graduated to form
a conical outline, but in the form of a cylindrical surface the said rings being
arranged one above the other and all the annular passage-openings being of
equal diameter.
According to this improved valve, a large cross sectional passage is obtained
apon a comparatively small space. At the same time the resistance, offered
to the liquid, is reduced to a minimum. If the valve be arranged in a nine or

valve, is but slightly deflected from the direction of movement.
ful effect is further increased.
The metal rings are, as already mentioned, rigidly connected by stays or
ribs. The method of fixing the rings and the arrangement of the said rings
may be varied; moreover, the shape of the rings may, as in the case of the
elastic washers fixed between the rings, be varied according to size, system and
shape of the valve. In any case, however, it is of importance that the elastic
annular lips be, in an appropriate manner, tightly secured between the super-
posed metal rings.
I, BENEDICT HÜBBE, of 61, Wollankstrasse, Pankow, Berlin, in the Empire
of Germany, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:—
This invention relates to valves consisting of rings having annular openings
which are normally closed by the flanges of elastic washers secured between the
adjacent rings in such a manner as to admit of the passage of the fluid in one
direction only.
The series of rings and washers constituting the improved valve may be
arranged in the form of a cone or in cylindrical form, each complete ring con-
sisting of a rigid portion and an elastic portion or washer the flange of which
is arranged in such a manner as to form, in conjunction with the inner part of
the rigid ring, an annular valve for the passage of the fluid.
By means of this arrangement the sum of the cross-sections of the passage-
openings, formed by the valve rings is larger than in those valves, in which the
elastic annular washers are located in one and the same plane. Moreover the
elastic annular washers admit of being subjected to a higher pressure.
My invention is illustrated in the accompanying drawing, in which:
Figure 1 is a vertical section of a conical form of valve constructed according
to my said invention and
Figure 2 is a vertical section partly in elevation showing a cylindrical form of
my improved valve.
In the form of my invention shown in Figure 1 each of the superposed annular
valve rings is formed by a rigid ring consisting of an inner ring b and an outer
ring connected by means of ribs h and an elastic washer a having a lip or
flange a¹. The said elastic washers are held in position at their lower rims or
edges between the metal rings band b¹. The rings 61 are, moreover, so con-
structed, as to serve as abutments for the lips or flanges of the adjacent elastic
washers a.
In operation, the liquid, traversing the annular openings in the direction,
indicated by the arrows, forces open the elastic lips of the flanged washers a.
This form of valve has the advantage, that it is adapted for high pressures, as
the ring serving as an abutment for the flange of the elastic washer, forms,
as it were, a rigid stop which prevents the said flange from being forced down.
The part 6 of the ring constructed in the form of an abutment is preferably so

page_text: arranged, as to outwardly surround the elastic washer a so that on the one hand,
the flange of the washer is protected from injury through mechanical action,
while, on the other hand, the lip is prevented from opening too far. The upper-
most ring, according to this construction, is preferably made in the shape of a
hollow body F, serving as an air chamber. The lowermost ring is provided with
a central hub through which and the top of the air chamber is passed a
bolt d, in such a manner that the rings constituting the improved valve may
be firmly secured together by means of the said bolt and its nut d'.
The modified form of the valve shown in Figure 2 differs from that above
described with reference to Figure 1 in as much as the rings are not arranged
in the form of steps or graduated to form a conical outline but in the form of
a cylinder the said rings being arranged one above the other and all the annular
passage-openings being of equal diameter.
According to this improved valve, a large cross sectional- passage is obtained
upon a comparatively small space. At the same time the resistance, offered to
the liquid, is reduced to a minimum. The valve may be arranged in a valve
box or chamber A in any suitable manner and in this case a further advantage
is obtained, namely, that the liquid, as it traverses the valve, is but slightly
deflected from the direction of movement shown by the arrows in Figure 1.
Thus the useful effect is further increased.
The method of fixing the rings and the arrangement of the said rings may be
varied; moreover, the shape of the rings, as well as the elastic washers fixed
between the said rings may be varied according to size, system and shape of
the valve. In any case, however it is of importance that the elastic washers
be in an appropriate manner, tightly secured between the superposed metal
rings.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is
1. A valve consisting of one or more pairs of annular rings, each pair being
formed by a rigid ring and an elastic washer having an upright rim or flange
forming an annular lip and bearing against the rigid ring for the purpose of
closing the valve passage and adapted to open outward for the passage of the
fluid, substantially as set forth.
2. A valve of the kind referred to in Claim 1, in which the pairs of annular
rings are superposed in the form of a cone, substantially as shown and described.
3. A valve of the kind referred to in Claim 1, in which the pairs of annular
rings are superposed in the form of a cylinder, substantially as shown and
described.
4. The improved valve constructed arranged and operating substantially as
herein before described with reference to the drawing.
