Abstract
Abstract The invention relates to an apparatus, particularly a shower head for forming a plurality of vented jets. The apparatus has a device for producing individual jets. It also has at least one underlying air space and obstacles projecting laterally into the paths of the individual jets, which deflect the latter and, while mixing with air atomize the said jets. Passage channels, which can have vortexing portions and quieting portions are provided for each vented jet for further influencing the air/water mixture. Several individual jets are used for producing a single vented jet. The object of the invention is mainly intended for use in the sanitary field.

Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
104 words
An apparatus for forming a vented jet, comprising: a device for producing unvented individual jets, said unvented jets being directed along a flowpath in a flow direction, at least one air access space being located downstream of said device; and, a passage channel defining a linearly open passageway along the flowpath, the channel having walls defining obstacles projecting into the flowpath for atomizing the individual jets, at least two of the individual jets being directed into said passage channel and the obstacles for atomizing the individual jets projecting laterally of the channel wall into a path of at least one of the individual jets.
Claim 2
Independent Claim
104 words
An apparatus for forming a vented jet, comprising: a device for producing unvented individual jets, said unvented jets being directed along a flowpath in a flow direction, at least one air access space being located downstream of said device; and, a passage channel defining a linearly open passageway along the flowpath, the channel having walls defining obstacles projecting into the flowpath for atomizing the individual jets, at least two of the individual jets being directed into said passage channel and the obstacles for atomizing the individual jets projecting laterally of the channel wall into a path of at least one of the individual jets.
Claim 3
Dependent Claim
53 words
An apparatus according to claim 1, wherein the passage channel is unobstructed along an axial central passage opening having an internal diameter larger than a cross-section of an unvented individual jet and the flow direction of said individual jet being displaced with respect to the axis of the passage opening in the channel.
Claim 4
Independent Claim
29 words
An apparatus according to claims 1 or 2, wherein the obstacles, along the flow direction, project into the passage channel as lateral projections forming constrictions in the passage channel.
Claim 5
Dependent Claim
29 words
An apparatus according to claim 3, wherein the obstacles comprise edges on the walls of the channel, the edges being arranged in substantially perpendicular manner to the flow direction.
Claim 6
Dependent Claim
28 words

Claim 7
Dependent Claim
13 words
An apparatus according to claim 1, wherein the channel has an asymmetrical cross-section.
Claim 8
Dependent Claim
19 words
An apparatus according to claim 6, wherein the cross-section of the channel is eccentrically reduced in the flow direction.
Claim 9
Dependent Claim
27 words
An apparatus according to claim 6, wherein the obstacles project only from one side of the wall of the channel into the path of the individual jets.
Claim 10
Dependent Claim
27 words
An apparatus according to claim 1, wherein, in the flow direction of an individual jet, a plurality of successively arranged obstacles are provided for atomizing the jets.
Claim 11
Dependent Claim
12 words
An apparatus according to claim 9, wherein the obstacles have different shapes.
Claim 12
Independent Claim
20 words
An apparatus according to claims 9 or 10, wherein the obstacles constitute a step-like separating means for the individual jets.
Claim 13
Dependent Claim
12 words
An apparatus according to claim 1, wherein the channel is cross-sectionally rectangular.
Claim 14
Dependent Claim
24 words
An apparatus according to claim 12, wherein the cross-sectional shape of the channel varies in the flow direction and is round at the outlet.
Claim 15
Dependent Claim
20 words
An apparatus according to claim 1, wherein three to ten devices for producing individual jets are associated with the channel.
Claim 16
Dependent Claim
36 words
An apparatus according to claim 1, wherein a plurality of individual jets are associated with the channel and a direct path of at least one of the plurality of individual jets is free of the obstacles.
Claim 17
Dependent Claim
36 words
An apparatus according to claim 1, wherein in the flow direction, the channel has a plurality of portions, including a jet atomizing portion having the obstacles and at least one jet vortexing portion having cross-sectional variations.
Claim 18
Dependent Claim
22 words
An apparatus according to claim 16, comprising a plurality of channels, and wherein each channel has at least one jet shaping portion.
Claim 19
Dependent Claim
19 words
An apparatus according to claim 16, wherein the cross-sectional variations of the jet vortexing portion have a conical configuration.
Claim 20
Independent Claim
21 words
An apparatus according to claims 16 or 18, further comprising at least one air intake issuing into the jet vortexing portion.
Claim 21
Dependent Claim
22 words
An apparatus according to claim 19, wherein the air intake issues at a point of the jet vortexing portion having a constriction.
Claim 22
Dependent Claim
22 words
An apparatus according to claim 1, comprising a plurality of passage channels, and wherein the passage channels are interconnected by transverse channels.
Claim 23
Dependent Claim
32 words
An apparatus according to claim 1, comprising a plurality of passage channels, and wherein the passage channels are formed by openings in a plurality of axially superimposed bodies, the bodies being disks.
Claim 24
Dependent Claim
