I3 affording the mounting thereof on a suitable
support (not shown). This arrangement of the
port 8 and the brackets 3 makes possiblea ready
the end of the stem 23 and opens the valve I5
maintaining it open while the crank arm 33 en
gages the stem 22 and opens the valve I4. _Both
and eñcacious coupling or stacking of two or
more valve units as shown in Fig. 4 and as will
be hereinafter more fully described.
Valves I4 and I5 have stems of uniform diame
ter mounted in the bores 2 and 3 for controlling
the flow of iiuid from said bores into the outlet
ports 4 and 5. These valves are urged by springs
I3 to seat against the inner ends of tubular valve
seat member Il snugly fitted in the bores 2 and
3 and having marginal flanges I8 abutting annu
lar shoulders I9 in said bores. Ports 2B are pro
vided in the seat members I'I to afford commu
nication of the diametrically enlarged inner por
tions of the bores of said seat members with the
outlet ports 4 and 5 respectively.
Stems 22 and 23 for the valve members I4 and
valves are now open and ñuid will flow through
Cil
the bores 2 and 3 andout through the two outlet
ports 4 and 5 thereby delivering a greater amount
of fluid for an emergency servicing of parts or
part to be de-iced. The emergency operation
requires that the operator hold the handle in its
uppermost or emergency iiow position as shown
in dotted lines in Fig. 2 and upon release of the
handle the spring for the valve I4 will push the
handle back to normal flow position thereby mov
ing the cam 32 olf the stem 23 and disposing the
cam 3| in position to hold the valve I5 open while
the valve I4 is closed.
A feature important in this valve unit is that
the intercommunicating port 8 serves the pur
pose of connecting the bores 2 and 3 with one
I5 respectively, extend through the seat members 20 another and facilitates the coupling or stacking
I l and openings 24 in a plate 25 secured by 'screws
‘of two or more units together in an efficient man

ner as shown in Fig. 4. To do this the angular
closes the adjacent ends of the bores 2 and 3. Ex
brackets 9 on the valve units are removed and
pansible sealing rings 2l surround the valve stems

two units are thus coupled for independent op
and a cup-like valve member 33 of yieldable ma
eration except that the supply of pressure fluid
terial such as rubber or synthetic rubber which
'encompasses said head so as to present an annu
lar supplementary seal» against the associated seat
member Il' while surrounding the head 25 which i..
also engages the seat member. .The head 29 iits
snugly in the socket afforded by the member 33
land securely holds said member on the head. A
boss 35a on the member 3!) acts as keeper for the
vassociated spring I6.
In accordance with this invention the outer
'ends of the valve stems 22 and 23 project beyond
-the plate 25 so that they may be engaged by valve
operating means including cam surfaces 3I and
passes from one to the other of the units through
the connecting ports 8 and but one supply line
connected to one of the units need be used. With
'the plurality of valve units thus stacked, different
portions of the aircraft maybe serviced at will
and the units are compactly mounted and take up
but little room, it being unnecessary to run more
than two fluid lines from each unit except the one
to which the fluid supply line is connected. Fur
thermore, a distinct advantage results from the
u-se of the particular type of intercommunicat
ing ports 8 in a series of valve bodies stacked as
v32 and a crank arm 33. These cam surfaces andi 45 aforesaid, because the aligned ports 8 provide a„
straight unobstructed passage through the inter

handle 34 pivoted on a pin 35 carried by flanges
38 on the plate '25. The handle 34 is held in
proper position on the pin 35 by means of a spacer
`sleeve 37 and a spring 38 as shown in Figs. 1 and> 50

.In its neutral or off position the handle 34 ex
.tends downwardly andA outwardly from the pivot

mediate units of the series. This advantage re
-sults from the fact that only opposite side por
tions of said port 8 communicate with the pas
sages to which they deliver the incoming fluid.
Fig. 5 shows a diagram of a typical anti-icing
system as used in aircraft as when operating to
"supply a normal ñow of fluid, and which includes
a reservoir A, and a pump B for delivering fluid

normal flow outlet port 5 of the unit D and line

I claim:
`
‘
1. In a ñuid control valve unit, a body member Y
having a pair of valve-receiving bores therein in
a parallel adjacent relation to each other, means
bodies having through it a horizontal intercom- ,
municating port consisting of a bore the width of
which spans the space between the aforesaid ad
jacent enlarged end portions of said valve-con
taining bores and thereby affords communication
between the latter bores, said intercommunicat
ing ports alining with each other to form a .
passage within the assembled valve units extend
ing in the direction of their alinement, closure
means for the opposite ends of said valve-receiv
ing bores, said valve stems projecting slidably
through said closure means at one side of each
. valve body, means operatively related to'the pro
jecting portions of said valve stems to operate
for intaking fluid under pressure into one of said
the valves, inlet means for atleast one of said
bores, an intercommunicating port extending
valve bodies communicating with at least one of
through said body member and so positioned that
its width bridges the space between said bores at
its said diametrically enlarged bore portions, and `
a point intermediate of its ends to afford the pas- 1
sage of pressure fluid from one to the other of said
communicating ports at each end of the assem- n
bores, closure means to overlie a side of said body
member for closing either of the ends of said in- l
closure means forthe outer ends of said inter
Ab_led valve units.
