Interlocking valve with lever stop

The invention relates to a one-way mixer valve with a stop for a hand lever with the features specified in the preamble of claim 1.

In these mixing valves, a control member mounted in the valve housing can be moved with a hand lever, with a lever or Lowering movement of the hand lever regulates the flow rate and a swivel movement of the hand lever regulates the mixing ratio is set. Here it is known to limit the pivoting movement of the hand lever that is connected to the lever by the Pivoting rotatable head piece with a channel-like groove and a stop pin between the head piece and the stationary one To provide valve housing. In this known arrangement, however, a change in position of the stop is not provided, see above that e.g. protection against scalding by moving the stop forward on the hot water side is not possible.

The invention is based on the object of providing an adjustable stop for a mixing valve of the type described at the beginning to create, which allows an optional limitation of the pivot angle for setting the mixing ratio.

This task is carried out by the characterizing part of the claim 1 specified features solved. Other features

of the invention are specified in claims 2-3.

An embodiment of the invention is shown in the drawing and is described in more detail below. It shows

Figure 1 is a head piece of a mixing valve in longitudinal section;

FIG. 2 shows the head piece according to FIG. 1 in section in plane A-B;

FIG. 3 a stop sleeve;

FIG. 4 shows the stop sleeve in section in the plane C-D of FIG. 3;

FIG. 5 shows a longitudinal section of the stop sleeve;

FIG. 6 shows a plan view of the stop sleeve;

FIG. 7 shows a top view according to FIG. 6 rotated by 180 °.

A control member 2 can be moved in a valve housing 1 stored. The hand lever 3 is mounted in a jacket sleeve 4 rotatably mounted on the housing 1. To accommodate the The axis of rotation 31 of the hand lever 3 is a split bearing 41 embedded in the jacket sleeve in a form-fitting manner. The articulation of the hand lever 3 to the control member 2 takes place with a pin 32, which is in a fork-shaped, provided with a locking pin 22 head part 21 of the Control member 2 borders. For the rotatable mounting of the jacket sleeve 4 and to complete the valve housing 1 is on A cover 5 is firmly screwed onto a thread 51 on the valve housing 1. The lid is a hexagonal one

Provided approach 52 having a dumbbell surface, through which the head part 21 of the control member protrudes centrally.

On the extension 52, a contact sleeve 6 is fastened centrally to the dumbbell sleeve 4 and the bearing 41 by means of a corrugated toothing 61. To make a simple honing too enable, the dumbbell sleeve 4 is provided with a removable cover cap 42.

During the assembly, the cover 5 is first of all screwed non-rotatably onto the valve housing 1 with the insertion of the rotatably mounted skin sleeve 4. Then that split bearing 41 is inserted into the jacket sleeve 4 and the Hand lever 3 is pushed with its pin 32 into the head part 21 of the control member 2. Now the stop sleeve 6 with its slot 62, which is approximately the width of the Pin 32 corresponds, pushed over the pin 32 onto the shoulder 52. In the middle area of the stop sleeve is a recess 63 is provided in the wall over an area of approximately 180 °, with the boundary sides 64 of which Pivoting movement of the hand lever 3 can be limited.

Due to the relatively large number of corrugated teeth, an exact position of the cover 5 with its hexagonal surface to the valve housing 1 is not necessary, because if E.g. the stop sleeve is provided with serrated teeth of 24 teeth, the profile of which corresponds to the hexagonal surface, the stop by 15 each be offset per tooth.

This ensures that the stop sleeve 6 when the pin 32 hits the boundary sides 64 is securely held, is the weakened by the slot 62 lower region of the stop sleeve with the corrugated teeth 61 in an annular space 65 between the extension 52 and the jacket sleeve 4 or bearing 41

taken and supported.

If the adjustable mixing range is now to be limited or changed, e.g. by a To create bracing protection, the stop sleeve 6 is simply rotated accordingly onto the cover inserted, so that serving as a stop limiting page 64 for the hot water setting side accordingly is brought forward.
