초록 ▼

A cylindrical chamber accommodates an axially movable rod having a helically grooved portion of the periphery, to which a starting flow of liquid is fed via an inlet passage of said cylindrical chamber, outlet passages for discharging separate streams of liquid after splitting of the initial flow to users and for feeding one of the streams back to the initial flow being arranged on different sides of the inlet passage. The distances between the geometrical axes of the inlet passage and outlet passages for discharging liquid to users are substantially identical and equal to the length of the helically grooved portion of the rod. With such a construction of the splitter, liquid supply to users may be varied over a broad range with relatively small axial displacement of the rod.

대표청구항 ▼

A liquid flow splitter for splitting an initial flow of liquid into at least three essentially isolated streams of liquid comprising: a casing; a cylindrical chamber in said casing, said cylindrical chamber having a substantially smooth cylindrical inner peripheral surface; a throttling member slideably fitted within said casing; said throttling member including a cylindrical portion abutting said inner peripheral surface; first and second continuous interlaced helical grooves on an outer cylindrical peripheral surface of said cylindrical portion, said first and second continuous interlaced helical grooves extending from one end of said cylindrical portion to a second end thereof; means for permitting linear movement of said cylindrical portion without rotation between first and second axial positions in said cylindrical chamber; an inlet passage adapted for the passage of an initial flow of liquid into said cylindrical chamber; said inlet passage being positioned to impinge said initial flow of liquid directly on said first and second continuous helical grooves at all axial positions of said cylindrical portion between said first and second positions whereby liquid impinging on said helical grooves is split to flow in opposite directions between said helical grooves and said cylindrical inner peripheral surface until said liquid exits said first and second continuous helical grooves at first and second opposed ends thereof; a first outlet passage spaced axially a first distance in a first direction along said cylindrical chamber from the said inlet passage, said first distance exceeding a maximum position of said cylindrical portion in said first direction; second and third outlet passages spaced axially from said inlet passage a second distance in a second direction opposite to said first direction along said cylindrical chamber, said second distance exceeding a maximum position of said cylindrical portion in said second direction; said second and third outlet passages being circumferentially spaced about said cylindrical chamber; a first flow passage from an end of said first helical groove at said second end of said cylindrical portion to said second outlet passage; a second flow passage from an end of said second helical groove at said second end of said cylindrical portion to said third outlet passage; means for substantially isolating flow of liquid between said first and second flow passages; said first outlet passage being adapted for feeding back liquid therefrom to rejoin said initial flow of liquid; and said second and third outlet passages being adapted for feeding liquid therefrom to first and second users respectively.
