Title: Turning spray nozzle having variable delivery rate
Inventor: KUWABARA YOUHEI
IPC: F23D11/38
Filed: 1984-06-28
Abstract: PURPOSE:To allow the wider range of flow rate control by providing a movable member with a resilient means that biases an inlet toward contractive direction, said movable member being displaced in the direction of the inlet port expansion upon receiving feed liquid pressure. CONSTITUTION:When increasing spray amount, fuel oil is supplied at a high pressure. As the fuel oil pressures the pressurized part 34 of a slitter 18 via the intake port 44 of a flange 42, a movable member 14 is axially displaced toward the end of a spray nozzle 2 against the spring force of a spring 12, and the opening area of inlet 32a of a slit groove 32 is adjusted and expanded by the displaced distance of the movable member 14, and the volume of a vortex chamber 38 is also expanded. Because of this, the opening area of the inlet 32a is expanded, the flow coefficient is also increased, and as a result, the spray amount is increased. When reducing the spray amount, the delivery pressure is reduced. The movable member 14 is biased toward the rear end of the spray nozzle 2 to separate the end 16a from a stopper wall 22 to cause the opening area of the inlet 32a to be reduced. The volume of the vortex chamber 38 is also reduced to cause the flow coefficient to be reduced, and as a result, the spray amount is reduced due to the cross effect of the change of the fuel oil pressure and flow coefficient.

Abstract: PROBLEM TO BE SOLVED: To improve the operability by performing cover opening and cassette ejection with one button by controlling the cover opening operation of a front panel and the ejecting operation of a cassette enclosure while interlocking. SOLUTION: While a front panel 3 is closed, an open/close state detection circuit 4 supplies the high level of door close information to a microcomputer 6; and when an operation button 1 is depressed, a front panel open circuit 5 changes depression information of the operation button 1 to the microcomputer 6 from the low level to the high level simultaneously with control to open the front panel 3. At this time, an operation request signal is not outputted to a tape ejection circuit 2 because information from the open/close state detection circuit 4 is the high level, and consequently, only the front panel 3 is opened by depression of the operation button 1 when the front panel 3 is closed.  While the front panel is in the open state, the open/close state detection circuit 4 supplies the low level of information to the microcomputer 6; and when the operation button 1 is depressed, it is changed from the low level to the high level, and the operation request signal is outputted to the tape ejection circuit 2, and the tape ejection circuit 2 is operated to eject a tape.
