The apparatus includes a feed line for supplying the fluid, a housing for transmitting rotary movement, a rotatable shaft having a longitudinal axis and rotatably mounting the housing, the at least one nozzle mounted on the rotatable shaft, and the feed line is connected to the housing, the housing including a first channel for supplying the fluid from the feed line through the housing, a second channel formed adjacent to the housing for supplying the fluid from the first channel to the rotatable shaft irrespective of the rotatable position of the rotatable shaft, and a third channel arranged at least partially in the rotatable shaft for supplying the fluid from the second channel to the at least one nozzle.
Abstract:
A jet nozzle assembly including a socket to hold a nozzle plate having a jet nozzle, a stepped barrel fastened to the socket to hold a hollow shaft having a front cup, a coupling coupled to a water supply pipe, a connector connected between the hollow shaft and the coupling to guide water from the water supply pipe through a water passage on the hollow shaft, permitting water to be further driven out of the jet nozzle of the nozzle plate through spiral grooves on the front cup of the hollow shaft.
Abstract:
A rotating joint for a sprinkler that provides a substantially constant rate of rotation regardless of water pressure and flow rate fluctuations. The joint includes a stationary lower portion that is in fluid communication with a pipe that delivers pressurized water to the sprinkler, and a moveable upper portion rotatably connected to the stationary lower portion about a substantially vertical axis. The moveable upper portion rotates in response to tangential forces that are applied by an impulse arm carried on a barrel from which pressurized water is discharged. The rate of rotation of the moveable upper portion is controlled by a braking mechanism that includes a pair of disks rigidly attached to the stationary lower portion and a pair of breaking elements mounted on the moveable upper portion. The pair of disks are located between and are in frictional engagement with the pair of braking elements with the pair of disks being secured against rotational and axial displacement with respect to the stationary lower portion. Variations in water pressure axially displace the moveable upper portion with respect to the stationary lower portion so that a braking element exerts a frictional force on a disk that is proportional to the water pressure to result in a self-adjusting braking force.
Abstract:
A flexible appendage for use as a robot arm, controllable medical instrument, or simply a toy, has flexibly coupled segments defining an open lumen, and flanges protruding laterally of the axis. The flanges have passages for control lines spaced laterally from the axis. Each control line is fixed to a segment and can be pulled through the other segments from the proximal end. The control lines shorten a lateral side of the appendage to controllably bend it. Resilient couplings between the segments, leave open the lumen for passage of conduits or tools. The couplings can be helical springs wound with turns which abut at rest, such that the couplings elongate on the outside of a bend but do not compress on the inside, thereby maintaining the overall length of the appendage. The control lines are distributed around the axis, and can be arranged in ranks for controlling groups of the segments at different distances from the proximal end. The springs coupling proximal segments are more rigid than for distal segments, and the segments can be smaller and/or longitudinally shorter approaching the distal end.
Abstract:
A rigid primary conduit directs fluid into an arcuate manifold. The arcuate manifold includes a concave surface having a plurality of spray nozzles directed into the manifold in fluid communication with the primary conduit to direct individual spray applications about the surface of an associated pool filter to enhance cleaning thereof.
Abstract:
A dispensing apparatus including an airless ribbon nozzle having a nozzle tip formed with a nozzle bore tapering radially inwardly from an inlet end to a semispherical-shaped discharge end which intersects a rectangular-shaped discharge slot. The nozzle is mounted in position on a coating dispenser such that the inlet of the nozzle tip communicates with a coating passageway within the dispenser to receive coating material which is emitted from the discharge slot of the nozzle tip in a wide, splash-free, leaf-shaped pattern.
Abstract:
A fluid swivel coupling is provided for interconnecting two fluid conduits so as to permit relative rotational movement between the interconnected fluid conduits about two axes at the coupling which are perpendicular to each other. The swivel coupling includes a swivel body connectable to a fluid conduit and adapted to accept for rotational movement a spindle member including a "U" shaped yoke rotatingly supporting a fluid conduit connector between the arms thereof. The swivel coupling is provided with a passageway between the interconnected fluid conduits which is continuous and remains uninterrupted throughout the range of movement of the swivel coupling.
Abstract:
A valve for connection to the boom of a crop spraying aircraft for emission of chemicals includes a pressure actuated valve member disposed therein in order to provide positive flow of the chemicals when pumped through the valve and positive dripless turnoff when the pressure is removed from the chemicals. Further, the valve is produced in two pivotally connected sections having a gauge disposed thereon for controlling the spray angle of the emitted chemicals and to thereby adjust the swath covered at each pass.
Abstract:
A manually operated sprayer which comprises a pump mechanism including a secondary valve having a valve body normally pressed against a valve seat by a compression spring and valve-sealing means designed temporarily to obstruct the flow of a liquid even after the valve body slides in liquidtightness along the inner wall of a tubular piston and is released from the valve seat, and wherein the valve-sealing means of the secondary valve is integrally formed with the valve body, and slides in liquidtightness along the inner wall the tubular piston for a prescribed distance to be brought into an annular groove formed in the inner wall of the tubular piston, thereby taking the form of a skirt-like strip to be released from the liquidtight condition.
Abstract:
A universal mounting structure for supporting a fog generator discharge head used in applying insecticides. The universal mounting structure includes a first conduit means constructed of a pair of right angularly disposed conduit portions for defining an entrance passageway and a transfer passageway, with one of the conduit portions including means for connecting the conduit means to fog generator air blower means. The universal mounting structure includes a second conduit means constructed of a pair of right angularly disposed conduit portions for defining a transfer passageway and an exit passageway. The second conduit means is connected to the first conduit means so that adjacent conduit portions are coaxially aligned with each other for angular adjustment about a vertically disposed axis and includes locking means for securing the second conduit means in a selected angularly adjusted position relative to the first conduit means. The second conduit means exit passageway is constructed of a first conduit section connected in flow communication with the transfer passageway and a second conduit section coaxially connected to the first conduit section for angular adjustment about a substantially horizontally disposed axis and includes means for locking the second conduit section in a selected angularly adjusted position relative to the first conduit section. The second conduit section is provided with an exit port having a mounting plate for supporting a fog generator discharge head.
