Title: Trigger type sprayer
Inventor: TSUBAKI TATSUO
IPC: B05B11/00
Filed: 1995-01-30
Abstract: PURPOSE: To eliminate that the suction of a liquid or the discharge of air is obstructed by residual pressure by allowing the residual pressure generated at the push-in terminal of a pump piston at the time of the closing of an accumulated pressure emitting valve to flow out of a container through a groove and a pressure discharge passage. CONSTITUTION: A sprayer main body 1 is constituted by threading a mounting cylinder with the mouth neck part of a container having a liquid stored therein. When a trigger 13 is pulled, a horizontal reciprocal pump mechanism 14 is operated and a liquid is sucked up through a suck-up pump 3 to be pressurized to be supplied to a spray nozzle 12 through an ejection cylinder 11. An accumulated pressure emitting valve 143 is opened against a spring 17 in a pressurizing process when a pressure accumulating piston 1433 receives force from a pressurized liquid on the basis of the diameter difference with a small diameter skirt 1434.  The residual pressure generated in a pump cylinder 141 accompanied by the opening of the accumulated pressure emitting valve 143 flows out from a groove 145 breaking watertightness to an exhaust passage 146 at the push-in terminal of a pump piston 142 and the pressure in the pump cylinder 141 lowers rapidly and suction is not obstructed.

In a fluidic element 3 provided in a flow path 2, a fluid entering a nozzle part 3a from a direction of an arrow A flows alternately to a direction of an arrow B and to a direction of an arrow C, thereby generating pulsations. The pressure of the pulsations is taken out from the detecting ports 3b, 3c, and the differential pressure between the ports 3b and 3c is converted to an electric signal by the element 1. Unnecessary high frequency components of the electric signal are removed by filter 4, so that an output voltage F(t) is obtained. The integrating time of each integrating circuit 7, 8 is controlled based on short pulse signals output for every cross point t1-t3 from a cross point detecting circuit 9. The integrated value is taken and multiplied by a proportional constant, and so on, thereby to operate the mass flow rate.
