Abstract: The viscous material metering feed has a body (2) with a reservoir for the material mounted above its central section. The rear end of the body is closed by a plug (5) through which passes a shaft (8) carrying a piston (9) at its inner end. The shaft also has a spacer (10) with a shoulder (11) around which is mounted a circlip (12), and a small piston (15) engaging a cylindrical sleeve (14). - The chamber wall (3) has a circular groove (21) adjacent the reservoir passage (4). The opposite end of the housing has a conical cap (23) in which is a diaphragm (30) forming a flow control valve.  (1/7) EPAB- EP-187886 B A machine for automatically dosing materials of various viscositites, conprising a hollow cylinder (2) with a vertical hopper (1) on top, which cylinder (2) forms an inner housing (3) in communication with the hopper (1) through an opening (4), said housing having a discharge mouth (25) at one end, the other end being closed by  a cap (5) with an opening for the passage of a rod (8); and an intake channel goes through said cylinder (2) near the cap and brings compressed air behind a large piston (9) and said cap is mounted peripherally and has an inside shoulder (6) with a central opening (7) running through it for the passage of the rod (8), which rod bears, inside the housing; the said large piston (9), a spacer (10) fitted with a shoulder (11) and a small piston (15) housed in a cylinder (14); wich small piston (15) is held at the end of the rod (8) inside the housing, said rod (8) carrying a circular stop (28) at its rear end, outside the housing; the cylinder (2) is extended at the end opposite the cap by a cone (23) enclosing a valve (27) and bearing at its end the discharge mouth (25) with a rubber tube extension (32); and the machine is characterised by a circlip (12) compressed against against the shoulder (11) of the spacer (10) by the inner wall of the housing (3), which circlip (12) is made of a resilient material allowing it to extend diametrically into a circular groove (21) to free a passage for the spacer (10) which groove is provided in the wall of the housing (3) near the opening (4) of the hopper (1) in communication with the cylinder (2); the machine being further characterised by the cylinder (14) having at its rear end a radially extending inward angle (13) located between the circlip (12) and the small piston (15) and further characterised by a coil spring (17) being placed beyond the cap (5) around the outer portion of the rod (8), the stroke of the said coil spring being adjusted by means of a sleeve (20) the inside of which is screwed on to - EP-187886 B A machine for automatically dosing materials of various viscosities, conprising a hollow cylinder (2) with a vertical hopper (1) on top, which cylinder (2) forms an inner housing (3) in communication with the hopper (1) through an opening (4), said housing having a discharge mouth (25) at one end, the other end being closed by  a cap (5) with an opening for the passage of a rod (8);

The hollow body contains in a rear part a piston which is arranged to push forward an assembly of movable elements including a cross-piece, a piston, a sleeve and a resilient slit ring. - This expels a product dose through a cone formed with holes and loosely lined in the interior with an elastic membrane. The movable elements are returned to their initial position by the force of a spring. The cone is extended by a pouring spout, which in turn carries a tube provided with a distributor cone.
