Abstract

To provide for different angles, including a right angle, at the discharge end of a mixing valve spout 4 with coaxial pipes 5, 6 for cold and hot water, there is provided an angled, detachable moulded jet concentrator with an outer 7 and an inner tube sealed by O-rings 11, 10 with pipes 5, 6 respectively. <IMAGE>

Description

SPECIFICATION A discharge spout for a mixing valve As far as mixing valves are concerned, it is a requirement in certain countries that the cold water is separated from the hot water. Therefore, separate flow passages have been provided in both the valve casing and the discharge spout. Accordingly, a mixing of the cold and the hot water cannot take place until after the water has left the discharge opening of the discharge spout.
The discharge spouts in question normally consist of concentric tubes. At the discharge end a jet concentrator is normally provided, said jet concentrator securing the inner tube relative to the other tube.
It is limited how sharply such a doublebarrelled tube flexure may be bent. Accordingly, the known discharge spouts have only been bent with comparatively large radii of curvature.
Therefore, it is object of the invention to show how it is possible to obtain a sharper change of direction of the jet direction, and according to the invention this object is obtained by a moulded body in the form of a double-barrelled tube flexure being mounted at the discharge end of the discharge spout, said tube flexure acting as a jet concentrator and angular flexure. Both flow passages in the double-barrelied angular flexure are at the discharge end provided with ribs cast integral with said angular flexure, said ribs producing the desired jet character. Furthermore, the ribs secure the inner tube relative to the outer tube.Such tube flexures may provide a comparatively great angular flexion, for instance an angular flexion of about 90 , and as the jet concentrating ribs are integral with the tube flexure a possible falling-out of the concentrator is avoided. The tube flexure is easy to mount and may be substituted by other tube flexures.
The invention will be described below with reference to the accompanying drawing, in which Figure 1 is a mixing valve with a discharge spout according to the invention Figure 2 is a front view of the mixing valve as shown in Fig. 1, Figure 3 is the discharge spout, viewed from below, and Figure 4 is a sectional view of the discharge spout.
The mixing valve shown in Fig. 1 contains a valve casing 1, a pivotai grip 2, 3 for cold and hot water, respectively, and a pivotal discharge spout 4. The discharge spout contains two concetric metal tubes 5, 6 which may be bent. However, it is limited how sharply such a double-barrelled tube flexure 4 may be bent. Accordingly, the known discharge spouts have only been bent with comparatively large radii of curvature.
According to the invention a moulded body in the form of a double-barrelled tube flexure of plastics is mounted at the discharge end of the discharge spoutcf. Figs. 1 and 4. The moulded tube flexure acts as a combined jet concentrator and angular flexure. It is easy to mount. The outer-tube 7 is connected to the inner tube 8 through ribs 9-cf. Fig. 3. There may be provided tightenings in the form of Orings 10, 11 in special grooves 1 2, 1 3 at both the inner and the outer flow passage.
The O-ring for tightening at the outer flow passage may be situated in a groove 1 3 in the outer surface of the outer flow passage 5 of the discharge spout.
The combined jet concentrator and angular flexure may advantageously be secured relative to the discharge spout by means of an inner control tap 14 in the angular flexure, said control tap fitting in a notch in the outer tube 5 of the discharge spout.
The combined jet concentrator and angular flexure is easy to mount and may easily be substituted by another combined jet concentrator and angular flexure to obtain an angular flexure which is different from the angular flexure of 90 .
The combined jet concentrator and angular flexure has an outer diameter of about 27 mm.
The combined jet concentrator and angular flexure is easy to mould, as the completed moulded body is not very long.
It is possible to vary the combined jet concentrator and angular flexure in many ways without deviating from the idea of the invention.
1. A discharge spout for a mixing valve comprising concentric tubes (5, 6) which may be bent, characterised in that at the discharge end of the discharge spout is mounted a moulded body in the form of a double-barrelled tube flexure (Fig. 4) acting as a jet concentrator and angular flexure.
2. A discharge spout as claimed in claim 1, characterised in that the combined jet concentrator and angular flexure (Fig. 4) is ready to be mounted and may be substituted by another combined jet concentrator and angular flexure.
3. A discharge spout as claimed in claims 1 and 2, characterised in that the ribs (9, 16) of the jet concentrator are cast integral with the combined jet concentrator and angular flexure.
4. A discharge spout as claimed in claim 1, characterised in that the combined jet concentrator and angular flexure is secured to the outer tube (7) of the discharge spout by means of a pair of inner ribs (9) in the socket of the angular flexure and the outer tube of the discharge spout.
