Abstract

1,272,530. Spray guns. SPRAYING SYSTEMS CO. 15 May, 1970 [15 May, 1969], No. 23683/70. Heading B2F. [Also in Division F2] In a spray gun the barrel has formed therein a chamber 26 having a fluid supply means 16, a nozzle supply seat communicating with the nozzle, a fluid return seat 32, communicating with a fluid return line 19, valve means 38, 39 spaced apart and fixed to a moveable member within chamber 26 in such a manner that when valve means 38 seats against the nozzle supply seat the valve means 39 is spaced from seat means 32 and vice versa said moveable member communicating with the valve actuating means. The valve means 39 may be tapered so that the flow through return line 19 is variable according to the position of valve means 39 relative to seat means 32. A second chamber 36 is sealed with a seal 37 through which the moveable member is slideably fitted. Contained within chamber 36 is a piston 45. The part of chamber 36 to the rear of the nozzle communicates with chamber 26 via orifices 43, 44 and an interconnecting passage in the moveable valve member. The area of piston 45 is such that the pressure on it substantially counteracts the pressure on valve means 39 when fully seated against seat 32. As shown in Fig. 7 a stop mechanism is provided on the trigger of the gun. This mechanism comprises a stop element 49 slidably mounted on rod 47a (the rear end of rod 15) having flat faces 50, 51 on which is mounted a knurled edge 54. In the position shown in Fig. 7 the flat faces 50 and 51 pass between the flanges 52, 53 on which the trigger is mounted, allowing the trigger to be fully pulled back. Using the knurled edge 54 the element 49 may be rotated through 90‹ thereby blocking the motion of the trigger.
