Abstract

Abstract This transducer includes the usual fluid beam-forming nozzle and output ports from which variable fluid streams are designed to issue. The proportion of fluid output is determined by an electromagnetically actuated deflector disposed between the nozzle and output ports for movement in response to electrical signals. The deflector has a rounded fluid beam deflecting surface movable relative to the path of the fluid beam.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 120 words
An electrofluidic transducer, comprising: a. means forming a nozzle opening and at least one output port spaced therefrom, said nozzle opening receiving fluid under pressure from a source and directing a fluid beam in the general direction of the output port; and b. means disposed adjacent said nozzle opening and said output port for varying the portion of said beam flowing into said output port, said means being supported for movement and having a deflector with a rounded beam engaged surface presented to said nozzle opening, said surface being of a width at least substantially equal to that of said nozzle opening, said deflector being movable at least partially across said nozzle opening and into the path of said beam.
Claim 2
Dependent Claim 120 words
An electrofluidic transducer, comprising: a. means forming a nozzle opening and at least one output port spaced therefrom, said nozzle opening receiving fluid under pressure from a source and directing a fluid beam in the general direction of the output port; and b. means disposed adjacent said nozzle opening and said output port for varying the portion of said beam flowing into said output port, said means being supported for movement and having a deflector with a rounded beam engaged surface presented to said nozzle opening, said surface being of a width at least substantially equal to that of said nozzle opening, said deflector being movable at least partially across said nozzle opening and into the path of said beam.
Claim 3
Dependent Claim 35 words
The electrofluidic transducer of claim 1 in which an electromagnetic means is provided, said electromagnetic means having an armature to which said deflector means is secured for movement thereby in the path of said beam.
Claim 4
Dependent Claim 31 words
The electrofluidic transducer of claim 2 in which a pair of output ports are provided and the deflector means is cylindrical and extends transversely of the path of the fluid beam.
Claim 5
Dependent Claim 49 words
The electrofluidic transducer of claim 3 in which the deflector is normally disposed adjacent one side of the nozzle opening and one of the output ports substantially registers with said nozzle and the other output port is disposed at the opposite side of the beam from said deflector means.
Claim 6
Dependent Claim 61 words
The electrofluidic transducer of claim 3 in which said deflector is of a diameter at least twice the width of the nozzle opening and the output ports of said pair are disposed to receive substantially equal portions of a fluid beam issuing from said nozzle opening when said deflector is disposed to be engaged by a predetermined portion of said beam.
Claim 7
Dependent Claim 150 words
A electrofluidic transducer, comprising: a. means forming a nozzle and a pair of output ports spaced therefrom, one output port substantially registering with said nozzle and the second being at one side thereof, said nozzle receiving fluid under pressure from a source and creating a fluid beam for discharge through the output ports; b. means disposed between said nozzle and output ports for varying the portions of said beam flowing into said output ports, said means having a cylindrical deflector of maximum diameter equal to the width of the nozzle and disposed at the opposite side thereof from said second output port, said deflector normally being disposed at the edge of the path of a fluid beam issuing from said nozzle and movable transversely of such beam; and c. electromagnetic means for moving said deflector, said electromagnetic means having an armature to which the deflector is secured for movement thereby.
Claim 8
Dependent Claim 150 words
A electrofluidic transducer, comprising: a. means forming a nozzle and a pair of output ports spaced therefrom, one output port substantially registering with said nozzle and the second being at one side thereof, said nozzle receiving fluid under pressure from a source and creating a fluid beam for discharge through the output ports; b. means disposed between said nozzle and output ports for varying the portions of said beam flowing into said output ports, said means having a cylindrical deflector of maximum diameter equal to the width of the nozzle and disposed at the opposite side thereof from said second output port, said deflector normally being disposed at the edge of the path of a fluid beam issuing from said nozzle and movable transversely of such beam; and c. electromagnetic means for moving said deflector, said electromagnetic means having an armature to which the deflector is secured for movement thereby.
Claim 9
Dependent Claim 110 words
An electrofluidic transducer, comprising: a. means for forming a nozzle and at least one output port spaced therefrom, said nozzle receiving fluiD under pressure from a source and creating a fluid beam for discharge through the output port; b. means disposed adjacent said nozzle and said output port for varying the portion of said beam flowing through said output port, said means having a concave beam-engaged deflector surface movable relative to the path of said beam; and c. an electromagnetic means provided adjacent said deflector means to move the same relative to said beam, said electromagnetic means having an armature to which the deflector means is secured for movement thereby.
Claim 10
Dependent Claim 110 words
An electrofluidic transducer, comprising: a. means for forming a nozzle and at least one output port spaced therefrom, said nozzle receiving fluiD under pressure from a source and creating a fluid beam for discharge through the output port; b. means disposed adjacent said nozzle and said output port for varying the portion of said beam flowing through said output port, said means having a concave beam-engaged deflector surface movable relative to the path of said beam; and c. an electromagnetic means provided adjacent said deflector means to move the same relative to said beam, said electromagnetic means having an armature to which the deflector means is secured for movement thereby.
Claim 11
Dependent Claim 88 words
An electrofluidic transducer, comprising: a. means for forming a nozzle and a pair of output ports spaced therefrom, said nozzle receiving fluid under pressure from a source and creating a fluid beam for discharge through the output ports; b. means disposed adjacent said nozzle and said output ports for varying the portion of said beam flowing through said output ports, said means having a pair of concave beam-engaged deflector surfaces; and c. an electromagnetic means having an armature to which the deflector means is secured for movement thereby.
