Abstract

A shower has a housing defining an axis, a conduit in the housing normally supplied with water under pressure and having an axially forwardly open outlet end, and a shower head having an axially rearwardly directed face axially confronting the outlet end and rotatable on the housing about the axis. The shower head is provided with at least two sets of axially forwardly directed spray nozzles and is formed with respective axially rearwardly open passages connected to the sets of nozzles. A seal disk extending across the axis between the outlet end and the rear face of the shower head is formed with an axially throughgoing hole and is fixed in the housing against rotation about the axis while being limitedly axially movable in the housing. An elastically compressible seal ring engaged axially between the outlet end of the conduit and the seal disk around the seal-disk hole presses the seal disk axially forward against the rear face of the shower head.

Claims

1. A shower comprising:

a housing defining an axis;

a conduit in the housing normally supplied with water under pressure and having an axially forwardly open outlet end;

a shower head having an axially rearwardly directed face axially confronting the outlet end and rotatable on the housing about the axis, the shower head being provided with at least two sets of axially forwardly directed spray nozzles and being formed with respective axially rearwardly open passages connected to the sets of nozzles;

a seal disk extending across the axis between the outlet end and the rear face of the shower head, formed with an axially throughgoing hole, fixed in the housing against rotation about the axis, and limitedly axially movable in the housing; and

an elastically compressible seal ring engaged axially between the outlet end of the conduit and the seal disk around the seal-disk hole and pressing the seal disk axially forward against the rear face of the shower head.

2. The shower defined in claim 1 wherein the housing includes a core element formed with

a stem on which the disk is rotationally fixed,

a rim axially engaging the ring, and

an axially throughgoing hole having an end

communicating with the seal-disk hole and an opposite end selectively alignable depending on angular position of the head with the passages.

3. The shower defined in claim 2 wherein the rim is hermetically bonded to the outlet end of the conduit.

4. The shower defined in claim 2 wherein the disk has an axially rearwardly directed peripheral shoulder axially engaging the ring.

5. The shower defined in claim 2 wherein the shower head includes

a diverter element formed with the passages and having a rear face at which the passages open.

6. The shower defined in claim 5 wherein the disk is made of a synthetic resin with a low coefficient of friction.

7. The shower defined in claim 5 wherein the diverter element is rotatable about the axis on the stem.

8. The shower defined in claim 5 wherein the rear face is formed around at least one of the passages with an annular and axially rearwardly open groove, the shower head comprising an O-ring seated in the groove and axially rearwardly engaging the disk.

9. The shower defined in claim 2 wherein the core element is formed with ribs extending to the rim and axially engaging the ring.

10. The shower defined in claim 2 wherein the disk is formed with two such holes diametrally spaced from each other relative to the axis and the shower head is formed for each set of nozzles with two such passages diametrally offset from each other.
