There is provided is a blower installed at a manhole opening, with which it is possible to facilitate an entry or an exit of a worker or an import or an export of an article. The present invention provides a ventilation system in a pipe conduit using the blower. Provided is a blower comprising: a ring-like or circular arc-like frame; a nozzle installed continuously or discontinuously along the frame; and compressed air supplying means for supplying the nozzle with compressed air, wherein the compressed air supplied from the compressed air supplying means is emitted while swallowing up air in the nozzle or near the nozzle, whereby, an airflow to a normal direction of a disk surface of which the flame is periphery is generated. The nozzle may be a nozzle for exhausting an air flown from an entry port of a cylindrical flow channel to an exit port of the cylindrical flow channel, and a plurality of the nozzles may be discontinuously installed along the frame.

Provided is a foreign matter removing apparatus at a track branch, and a nozzle used in this apparatus that are capable of sufficiently securing foreign matter removing performance as well as significantly reducing generation of noises. In the nozzle for the foreign matter removing apparatus 100 at a track branch, compressed air PA supplied from piping 180 is injected from each nozzle element 110. Slits 140 are formed in each nozzle element 110, a sloped portion 130 is formed at a front end of the nozzle element 110, and this sloped portion 130 opposes a tongue rail 502.

A device (1) for a controlled discharge of a main fluid according to the present invention comprises at least one passageway (13) for the main fluid. The at least one passageway comprises at least one inlet (11) for the main fluid and at least one outlet (15) for the main fluid. The at least one outlet for the main fluid can be blocked by a movable block (16) further comprised in the device, the movable block operable to alternate between a first and a second position. When situated at the second position, the movable block closes the at least one outlet for the main fluid. The device according to the present invention further comprises a least one inlet (12) for a drive fluid. Responsive to a drive fluid supply through the at least one inlet for the drive fluid, the movable block moves from the first position towards the second position. A method of operating a main fluid's discharge from a passageway comprises supplying a drive fluid so as to press the movable block towards the second position.

A rotary sprinkler (100) comprises first, second and third nozzles (104A, 104B, 104C). The first nozzle comprises a first nozzle fluid pathway (122A) including a central axis (140), an inlet (120), an outlet (124), a first length (154A) measured from the inlet to the outlet along the central axis, and a first interior diameter (142A) at the outlet. The second nozzle comprises a second nozzle fluid pathway (122B) including a central axis (140), an inlet (120), an outlet (124), a second length (154B) measured from the inlet to the outlet along the central axis, and a second interior diameter (142B) at the outlet. The third nozzle comprises a third nozzle fluid pathway (122C) including a central axis (140), an inlet (120), an outlet (124), a third length (154C) measured from the inlet to the outlet along the central axis, and a third interior diameter (142C) at the outlet. In some embodiments, the first interior diameter is greater than the second interior diameter, and the second interior diameter is greater than the third interior diameter. In some embodiments, the first length is greater than the second length, and the second length is greater than the third length. A sprinkler system comprises a plurality of rotary sprinklers (100), an irrigation controller (306) and a system controller (274). The rotary sprinklers each comprise a water supply inlet (108), a nozzle head (102) supported by a base (106), and a plurality of nozzles supported by the nozzle head. The nozzles each comprise a fluid pathway (122) having an inlet (120) and an outlet (124). A fluid flow path (114, 116) connects the water supply inlet to the inlets of the nozzles.
