Abstract
A flow coupling, with a valve, comprises a pipe-shaped housing for the non-return valve, and a coupling pipe (14), which in the coupled setting causes a valve element (13) of the valve to be moved into open setting. For this purpose, a pipe-shaped displacing member (31) with detent means (33, 34, 40) for a defined valve opening range is arranged between the coupling pipe (14) and the valve element (13). <IMAGE>
Description
SPECIFICATION
Valved flow coupling
The present invention relates to a valved flow coupling.
In the specification of German (Fed. Rep.) patent application P 32 46 127.5 there is disclosed a liquid coupling with a non-return valve, in which a connecting stub pipe of a hose duct enters into the pipe-shaped body of the valve in the coupled setting to such an extent that it displaces a pipe-shaped plunger of the valve against spring pressure until a sealing collar of the valve lifts off a seat and openings thereunder produce a flow path between the two sides of the valve.
In order that, for the storage and metering of washing or rinsing agents in respective couplings, defined flow resistances can be adhered to, which resistances can have an influence on the metering process, at least the opening width of the valve in the coupling setting must be of uniform size.
To obtain a defined valve opening width, all tolerances must be close and maintained very
precisely. On coupling, strict adherence to the constructionally provided coupled setting must be observed.
The first-mentioned condition leads to costly finishing, which should be avoided in mass production for the consumer goods industry.
Moreover, adherence to this condition means that consistent reproducibility of the valve opening width would not always be possible, because according to the second-mentioned condition
operator errors cannot be excluded.
It would thus be desirable to eliminate the
afore-mentioned restrictions so that in the
construction and use of such a coupling larger
tolerances and operating irregularities are without 'effect on the flow resistance in the coupling.
According to the present invention there is
provided a valved flow coupling compris#ing a
housing, a substantially tubular displacing
member movably arranged in the housing, a valve
element arranged in the housing to be
displaceable by the displacing member through a
defined stroke from a closed setting into an open
setting, detent means to limit movement of the
displacing member thereby to define said stroke,
and a pipe coupling member insertable into the
housing to effect movement of the displacing
member and thereby displacement of the valve
element into the open setting, the displacing
member being disposed between the valve
element and the coupling member in the inserted
state of the latter.
The displacing member with the detent means
can be entrained by the movement of the coupling
member until detenting of the detent means,
which occurs in a defined setting and thereby
reproducibly determines the opening width of the
valve. The detenting is thereby independent of the
extent of entry of the coupling member into the
housing and thus is not externally influenced.
An embodiment of the present invention will now be more particularly described by way of example with reference to the accompanying drawings, in which:
Fig. 1 is a sectional elevation of a flow coupling embodying the invention, the coupling being shown in its separated state; and
Fig. 2 is a view similar to Fig. 1 but showing the coupling in its coupled state.
Referring now to the drawings, there is shown a flow coupling in which, for ease of understanding, the components are provided with same reference numerals as in the afore-mentioned German patent application P 32 46 127.5. The coupling comprises a housing consisting of a valve body 11, which in the previously illustrated way can be inserted into an opening of a storage container, and of a valve casing 24 connected to the (in use) inwardly projecting end of the body 11 , the casing 24 being provided at one side with an inflow opening to a valve chamber 26. Arranged in the chamber 26 is a valve element 13 which is pressed by a spring 12 against a valve seat 27.
The valve element and seat control a flow connection between the chamber 26 and an outwardly leading pipe duct 28. The casing 24 is connected with the body 11 by a spring ring 29.
At its outlet side the valve element 13 has a pipe-shaped plunger 30, which contacts a pipeshaped displacing member 31. The member 31 is slidably mounted in the body 11 and is provided, in a circle plane 32, with two detent balls 33, which are retained with play in openings 34 provided therefor. The diameter of each ball 33 is such that in the uncoupled state of the coupling it does not project into the duct 28 by more than one half diameter. Preferably, this amount of projection is smaller than a half diameter, the openings 34 being somewhat narrowed towards the wall of the bore in the member 31 so as to prevent the balls from falling into the duct 28.
At its coupling end, the body 11 is internally fitted with a guide sleeve 35, which is held in place by a spring ring 36. A sealing ring 37 provides a seal between the sleeve 35 and the body 11, while a further sealing ring 38 at the inner side of the sleeve 35 serves to provide a seal between the sleeve and a coupling pipe 14. An inner cone of the sleeve 35 serves for centring the pipe 14 when moved into the coupling setting, while an outer cone of the pipe serves for centring within the coupling setting. In that setting, a collar 1 5 of the pipe 14 rests, as shown in Fig. 2, on the end surface of the body 11. A stub 1 6 serves for connection with a hose.
For production of the coupling and opening of the valve element 13, the pipe 14 is pushed into the duct 28, in which case the pipe 14 first passes the sealing ring 38 and produces a sealed connection in the duct 28. On further insertion of the pipe, the forward end surface 39 thereof presses, through the balls 33, the member 31 forward until the balls engage in an annular channel 40, the depth of which is such that the balls are disposed clear of the bore 28. The pipe 14 can now be pushed in past the balls even deeper into the duct 28.
The member 31 is locked in this setting through the engagement of the balls 33 in the channel 40 and during movement into this setting presses, through the plunger 33, the valve element 13 against the pressure of the spring 12 and into a defined open setting. In this setting, the content of an associated container can flow through the outflow opening 25, the chamber 26, openings 41 in the plunger 30 of the valve element and the duct 28 to the pipe 14.
The opening range of the valve element 13 is defined in the coupling setting by the sum of the length a of the plunger 30 and the spacing b of the contact surface between the plunger 30 and the member 31 to the plane 32 of the balls 33, less the spacing c of the circle plane 42 of the channel 40 to the valve seat 27. As these spacings are constructionally fixed and thus unchangeable, the opening range of the valve is also unchangeably fixed independently of the depth of insertion of the pipe stub 14 in the duct 28.
