The elastic means (E) is secured, at each of its ends, to an articulation member (20a, 20b) respectively accommodated in a housing (21, 22) provided on the connecting rod and on another moving part (18) of the machine, each housing (21, 22) being open in a direction substantially opposed to the direction of the force exerted by the elastic means (E) in the housing, such that each articulation member (20a, 20b) can be removed from its open housing (21, 22) against the action of said force, thereby simplifying assembly and disassembly.

EQUIPMENT FOR MEASURING AND INJECTING AT LEAST TWO PRODUCTS INTO A LIQUID CURRENT
The invention concerns an equipment for measuring and injecting at least two products into a main liquid current, comprising at least two metering devices (DA, Db) mounted in parallel, each metering device including a hydraulic motor actuated by the main liquid and pumping and injecting means driven by the hydraulic motor. A variable throttling means (Sa, Sb), whereof the passage cross-section can increases with the flow rate of the liquid passing therethrough, countering return means (Ra, Rb), is provided on the liquid current of each metering device (Da, Db), to create a supplementary pressure drop added to the one generated by the metering device itself.
The invention relates to a dosing device for introducing an additive (A) in to a main liquid flow (L) in a conduit comprising a reciprocating differential piston pump (2) which is used for collecting and dosing the additive (A) from a container (1) and comprises a first inlet (7) for receiving the main liquid flow which ensures the pump actuation, a second inlet (8) for collecting the additive and an outlet (9) for mixing the additive and the main liquid. The inventive device comprises a Venturi (10) disposed in the conduit and the pump (2) connected in parallel position with respect thereto, wherein the first inlet (7) of the pump is connected to the Venturi input (11) and the outlet thereof is connected to the Venturi throat (12).
