Abstract: An actuator for operating a fill valve of a bottle filling machine, said actuator having a camshaft provided with a cam fork on its inner end adapted to engage cam follower means on a fill valve, and having a trip lever on its outer end adapted to engage a rotating shoulder means on a turntable of the machine, the camshaft being rotatable within a sleeve bearing, wherein a braking means comprising a helical wave spring is mounted over the camshaft to provide a desired frictional resistance to rotation of the camshaft within the bearing for preventing rotational drift of the cam fork from its desired operating position.

Abstract: The invention discloses a tap (10) for controlling liquid flow. The tap (10) has a tube (14) with first (16) and second (18) opposite open ends, an inlet opening (20) leading into the tube between the first and second open ends, and an outlet opening (16) defined by the first open end (16), which outlet opening (16) serves as an outlet from the tube (14). The tap (10) further includes a first valve seat (36), formed between the inlet opening (20) and the outlet opening (16), and a second valve seat (38), formed between the inlet opening (20) and the second open end (18). A closure member (42) is sealingly slidably movable in the tube (14) and is provided with a first circumferential sealing edge (60), the first sealing edge (60) being adapted to removably abut against the first valve seat (36). The closure member (42) is further provided with a second circumferential sealing edge (66), the second sealing edge (66) being adapted to removably abut against the second valve seat (38).

Abstract: A housing (2) has an upper portion engaged with a cylindrical stopper member (20) in screw-thread fitting so as to be able to vertically advance and retract the stopper member (20). The stopper member (20) has an outer thread (20a) engaged with a nut member (21) and has an inner thread (20b) engaged with a thrust screw member (23) each in screw-thread fitting. The stopper member (20) has a stopping portion (A) which prevents the downward movement of the intermediate transmission member (25) connected to the thrust screw member (23) over a predetermined distance. This inhibits a metal diaphragm (12) from being excessively pushed to a valve seat (15). When further moving the diaphragm (12) for valve closing, the nut member (21) is loosened and at the same time the stopper member (20) is advanced downwards to thereby define a gap between a receiving portion (B) of the intermediate transmission member (25) and the stopping portion (A).

Abstract: A sealing system for use in a liquid/flowable product filling apparatus which comprises a hopper for holding the product, one or more filling assemblies, each of which includes a nozzle, a cylinder, a valve for selectively passing product from the hopper to the cylinder and from the cylinder to the nozzle, a piston selectively moveable in the cylinder to draw product from the hopper through the valve into the cylinder or to push product from the cylinder into the valve and out of the nozzle, and a plunger selectively moveable in the valve to prevent the flow of product from the hopper into the valve or prevent the flow of product from the valve and out of the nozzle. The sealing system includes an annular piston seal circumscribing the piston to press against the cylinder walls to provide a seal therebetween. The valve includes an annular wall section through which the plunger moves, and an annular recess formed in the wall section.

Abstract: A valve for use with a fluid tap is disclosed having a valve body (1), a handle spindle (3) which is termed to open and close a valve closure member (15). A valve carrier (8) is slidably mounted within the valve body (1) and includes an aperture (9) which receives a shaft (16) of the valve closure member (15). At least one of the handle spindle (3) and/or the valve carrier (8) is provided with a cammed surface (6,12) such that rotation of the handle spindle (3) through only fraction of a turn results in substantial longitudinal movement of the valve carrier (8), and subsequently, the valve closure member (15), relative to the valve body (1).
