The jet regulating device is provided in the form of a perforated plate having at least a perforated field in at least a partial area thereof. The spout device has a mounting sleeve that supports the jet regulating device on an outflow side sleeve end area thereof, and the mounting sleeve is joined to the water spout of the plumbing spout fitment via a screwed, clip, detent, adhesive or welded connection. The spout device has a comparatively low installation height that does not significantly limit design possibilities when designing associated spout fitments. The spout device also makes it possible to achieve a high jet quality and a good jet pattern. ## Claims ### Claim 1 A low-profile plumbing spout device (4) having an upstream portion and a downstream portion comprising a mounting sleeve (7) having a generally cylindrical configuration, with external threads that matingly engage internal threads of a plumbing spout (3), the mounting sleeve (7) comprising a flow-rectifying device (5) integral with the mounting sleeve (7) at an outlet end of the plumbing spout device (4) at the downstream portion. ### Claim 2 (depends on 1) The spout device according to claim 1, further comprising an attachment screen (6) at an inlet end of the spout device (4), the attachment screen (6) connecting to the mounting sleeve (7) such that the attachment screen (6) is housed substantially within the mounting sleeve (7) and extends only partially past the threads of the mounting sleeve (7). ### Claim 3 (depends on 1) The spout device according to claim 1, wherein the spout device (4) has a contoured outer end face tool attachment surface projecting axially beyond the thread in a flow direction for a tool insert. ### Claim 4 (depends on 1) The spout device according to claim 1, wherein the attachment screen (6) is connected immediately upstream of the flow rectifying device (5) without an intermediate connection of other installation parts or functional units. ### Claim 5 (depends on 1) The spout device according to claim 1, wherein a throughput regulator or a throughput limiter is connected upstream of the attachment screen (6) in the direction of flow. ### Claim 6 (depends on 1) The spout device according to claim 1, wherein the attachment screen (6) directly contacts a supply side of the flow rectifying device (5) at an outer edge region thereof. ### Claim 7 (depends on 1) The spout device according to claim 1, wherein the flow rectifying device is formed as a perforated plate having a honeycomb-like structure. ### Claim 8 (depends on 1) The spout device according to claim 1, wherein a height to diameter ratio of the mounting sleeve is less than 0.5. ### Claim 9 (depends on 1) The spout device according to claim 1, wherein a height to diameter ratio of the mounting sleeve is less than 0.6. ### Claim 10 A low-profile plumbing spout device (4), having an upstream portion and a downstream portion, comprising a mounting sleeve (7) having a generally cylindrical configuration, with external threads that matingly engage internal threads of a plumbing spout (3), the mounting sleeve (7) comprising a flow-rectifying device (5) integral with the mounting sleeve at an outlet end of the plumbing spout device (4) at the downstream portion, the flow-rectifying device being generally flush with a surface around the plumbing spout (3), a conical attachment screen (6) at an inlet end of the spout device (4) that is connected to the mounting sleeve, and a height to diameter ratio of the mounting sleeve is less than 0.5. ### Claim 11 (depends on 10) The spout device according to claim 10, further comprising an additional functional element to influence a jet quality of the device located between the conical attachment screen and the flow-rectifying device. ### Claim 12 A low-profile plumbing spout device (4), having an upstream portion and a downstream portion, comprising a mounting sleeve (7) having a generally cylindrical configuration, with external threads that matingly engage internal threads of a plumbing spout (3), the mounting sleeve (7) comprising a flow-rectifying device (5) integral with the mounting sleeve at an outlet end of the plumbing spout device (4) at the downstream portion, the flow-rectifying device being generally flush with a surface around the plumbing spout (3), a conical attachment screen (6) at an inlet end of the spout device (4) that is connected to the mounting sleeve, and a height to diameter ratio of the mounting sleeve is less than 0.6. ### Claim 13 (depends on 12) The spout device according to claim 12, further comprising an additional functional element to influence a jet quality of the device located between the conical attachment screen and the flow-rectifying device.
