Abstract (en)

[origin: EP1830065A1] A device for connecting a dosage pump to a hydraulic system; the pump (11) comprises a hollow body (12) whose head (13) accommodates a vaned element (14) which rotates due to the fluid which arrives from the hydraulic system; the fluid enters the head (13) through an intake port (15) and exits through a discharge port (16); the intake port (15) and the discharge port (16) are connected to appropriately provided corresponding connectors of the hydraulic system by interposition of a coupling (17) inside which an intake channel (18) and a discharge channel (19) for the fluid of the pump (11) are provided. On the head (13), the intake port (15) and the discharge port (16) are formed on a same side and are mutually laterally adjacent. On the coupling (17), which is provided by a substantially T-shaped body, the intake channel (18) and the discharge channel (19) each lie, for a first substantially straight portion (18a, 19a), between a port (20, 21) for connection to the hydraulic system and a curved portion (18b, 19b) in the central part (22) of the coupling (17) and, for a second portion (18c, 19c), with an axis (23, 24) which is transverse with respect to the axis (25, 26) of the respective first portion (18a, 19a), between the curved portion (18b, 19b) and an opening (18d, 19d) designed to face one of the two corresponding ports, the intake port (15) or the discharge port (16), of the head (13). The first portions (18a, 19a) of the two channels (18, 19) are mutually opposite with respect to the central part (22) inside the lateral arms (17a, 17b) of the T-shaped body that forms the coupling (17) and the two second portions (18c, 19c) lie within the central part (22) of the coupling (17).
