Abstract: Applicator (11) for application of a viscous mass (31) to a surface (33) comprising a heated chamber (32) in communication with openings (12) controlled by valves (14) allowing dropwise discharge of the viscous mass to the surface. The valves (14) are non-packed and comprise an outer sleeve (15) having at least one through opening (16) in its sleeve wall and valve plug (17) adapted to the internal surface of the sleeve (15). The valve plug (17) is reciprocated by a valve lifter (18) from a closed position completely sealing the at least one through opening (16) in the sleeve wall, to an elevated open position exposing at least the lowermost part of the at least one through opening (16) allowing viscous mass (31) to pass from the outside of the sleeve (15) to the inside thereof.

Abstract: Apparatus for depositing a flowable substance as marking on road surfaces, and the like, comprising a container for the flowable substance which is conducted through a valve with a series of computer controlled, close adjacently arranged valve elements which can be activated individually with a series of activating members with connecting elements to the individual valve elements. The apparatus comprises a way of varying as an assembly the geometry of the movement of activating members of the valve members. The connecting elements are linked to a longitudinally extending member with an eccentric mechanism to regulate the active length of the connection between the activating member and the valve member for each of a plurality of valve members.
