摘要：A spray valve assembly for an aerosol can has a valve housing (4) which can bepermanently inserted in the upper part (1) of the can with an upper end section (5) andbounds a main channel (21) for the contents of the can to pass through, and has in themain channel (21) a main valve (2, 3) with a hollow valve shaft (2) which can be actuated

manually counter to the force of a spring (10) and a rubber-elastic annular washer (3).The latter interacts as a valve closure element with at least one lateral valve opening (28)in the valve shaft (2). In addition, the housing (4) has a subsidiary channel (17) whichconnects the can space to the main channel (21) upstream of the main valve (2, 3). In orderto permit at least an economical consumption of the contents of the can by virtue of alow delivery speed, it is provided that the main channel (21) has a first restrictor section(25) between the main valve (2, 3) and the connection point of the main channel (21) andsubsidiary channel (17), that, in a branch channel (29) which leads from the subsidiarychannel (17) to the main channel (21) between the first restrictor section (25) and themain valve (2, 3), a second restrictor section (30) is located and that the restrictor cross-sections of the two restrictor sections (25, 30) are approximately the same and smallerthan 0.2 mm<2>.
