Multi-jet massager

Claim 2

A jet massage device comprising a housing having a chamber, fluid inlet means to said chamber, fluid outlet means from said chamber, said fluid outlet means comprising a first and a second outlet port exposed to said chamber and a first and second fluid nozzle, each of said ports being in fluid communication with a different one of said nozzles, rotary means in said chamber effective to be rotated by fluid passing through said chamber from said inlet means to said outlet means, and control means operably connected to and driven by said rotating means, said control means comprising an element attached to said rotary means and operably communicating with said outlet ports, said element having a surface portion shaped to obstruct said ports alternately but not to completely obstruct both ports simultaneously as said control means is driven by said rotary means.

Claim 3

The device according to claim 1 wherein said surface portion sealingly engages said outlet means to prevent fluid entrance into a port which is completely obstructed from said chamber by said surface.

Claim 4

The device of claim 2, said housing carrying a sealing member in said opening, said fluid outlet means member engaging said sealing member when said fluid outlet means member is received in said opening.

Claim 5

The device of claim 3, in which said member terminates in a surface directed into said chamber, said ports being on said surface, said control means element engaging and sliding over said surface as said control means rotates.

Claim 6

The device of claim 4, in which said rotary means comprising a body and a hub extending therefrom toward said member surface and comprising said element which engages and slides over said surface as said control means rotates.

Claim 7

The device of claim 5, in which said ports are contained within a given area, said hub element where it engages said surface having a cross sectional area less than said given area.

Claim 8

The device of claim 3, in which said rotary means comprises a body and a hub extending therefrom toward said conduit ports and engaging and sliding over said ports, thereby to comprise said control means.

Claim 9

The device of claim 7, in which said ports are contained within a given area, said hub where it engages and slides over said ports having a cross sectional area less than said given area.

Claim 10

The device of claim 1, in which said housing is provided with an opening communicating with said chamber, said fluid outlet means comprising a member sealingly received in said opening, exteriorly operatively connected to said nozzles, and having separate conduits for each of said nozzles respectively, each of said conduits terminating iN a separate port exposed to said chamber, said control means comprising an element operatively connected to said rotary means and moved thereby over said ports to alternately obstruct and open said ports.

Claim 11

The device of claim 9, said housing carrying a sealing member in said opening, said fluid outlet means member engaging said sealing member when said fluid outlet means member is received in said opening.

Claim 12

The device of claim 9, in which said member terminates in a surface directed into said chamber, said ports being on said surface, said control means element engaging and sliding over said surface as said control means rotates.

Claim 13

The device of claim 11, in which said rotary means comprises a body and a hub extending therefrom toward said member surface and comprising said element which engages and slides over said surface as said control means rotates.

Claim 14

The device of claim 12, in which said ports are contained within a given area, said hub element where it engages said surface having a cross sectional area less than said given area.

Claim 15

The device of claim 9, in which said rotary means comprises a body and a hub extending therefrom toward said conduit ports and engaging and sliding over said ports, thereby to comprise said control means.

Claim 16

The device of claim 14, in which said ports are contained within a given area, said hub where it engages and slides over said ports having a cross sectional area less than said given area.

Claim 17

The device of claim 1, in which said chamber is defined between a front wall, a rear wall and a substantially cylindrical side wall, said fluid inlet means entering said chamber adjacent said side wall, said rotary means comprising a vaned body operatively connected to a mounting shaft extending out therefrom at one end and having a hub extending out therefrom at the other end, said shaft being mounted on said rear wall, said hub extending toward said front wall, said front wall having an opening therethrough opposite said hub, said fluid outlet means having a surface exposed to said chamber by said opening and having first and second ports in said surface communicating with said nozzles respectively, said hub being located opposite said surface and being shaped to alternately obstruct and open said ports respectively as said vaned body rotates in said chamber, thereby to define said control means.

Claim 18

The device of claim 16, in which said hub engages and slides over said fluid outlet means, thereby to be axially located within said chamber.

Claim 19

The device of claim 17, in which said ports are contained within a given area, said hub where it opposes said surface having a cross sectional area less than said given area.

Claim 20

The device of claim 16, in which said ports are contained within a given area, said hub where it opposes said surface having a cross sectional area less than said given area.
