Liquid transfer device

Abstract

The invention relates to a liquid transfer device including: a connecting element which is to sealably attached onto a liquid transfer opening and which includes a set of liquid transfer ports, an outlet, and a bore that extends between the transfer ports and the outlet; and an adapter which is to be connected to liquid discharge means and which includes a head shaped such as to be inserted into the outlet and including a set of holes for engaging with said ports. Said liquid transfer device includes a swing joint placed in the connecting element between the outlet and the liquid transfer ports and includes a set of liquid passages and a recess shaped such as to receive the head of the adapter in a position in which said passages of the joint and the holes of the adapter are aligned. Said joint is rotatably movable in the connecting element, between a closed position of the device and a liquid transfer position, by means of the head of the adapter.

1 . A device for transferring liquid, the device comprising a connection element for fastening in leaktight manner in a liquid transfer orifice and having a set of at least one transfer port for transferring liquid into the connection element, an outlet orifice for discharging liquid from the connection element, and a bore extending between the transfer ports and the outlet orifice, an adaptor for connecting to liquid removal means and comprising a head shaped to be inserted in the outlet orifice and including a set of at least one hole for co-operating with said ports formed in the connection element, wherein the device includes a rotary shutter placed in the connection element between the outlet orifice and the liquid transfer ports and including a set of at least one liquid passage and a socket shaped to receive the head of the adaptor in a position in which said passages of the shutter and the holes of the adaptor are in alignment, said shutter being movable in the connection element under drive from the head of the adaptor to turn between a closed position of the device in which the shutter shuts the transfer ports, and a liquid transfer position in which said passages and said ports are in alignment. 
     
     
         2 . The device according to  claim 1 , including abutments for limiting turning of the shutter in the bore of the connection element. 
     
     
         3 . The device according to  claim 2 , including at least one transverse pin inserted through the rotary shutter and into a slot formed transversely in the adaptor. 
     
     
         4 . The device according to  claim 3 , wherein the slot is provided with end enlargements . 
     
     
         5 . The device according to  claim 2 , wherein the rotary shutter includes at least one radial extension snap-fastening in a slot formed transversely in the adaptor. 
     
     
         6 . The device according to  claim 1 , wherein the outlet orifice of the connection element and the socket of the shutter are polygonal in shape having a shape complementary to the shape of the head of the adaptor. 
     
     
         7 . The device according to any  claim 1 , wherein the shutter is arranged on the same axis as the outlet orifice. 
     
     
         8 . The device according to  claim 1 , wherein the passages of the rotary shutter, the ports of the connection element, and the holes of the adaptor are arranged radially. 
     
     
         9 . The device according to  claim 1 , wherein the shutter has six passages and the connection element has six liquid transfer ports. 
     
     
         10 . The device according to  claim 1 , further including a closure plug for closing the connection element. 
     
     
         11 . The device according to  claim 10 , wherein the plug has a flat head and a tail of shape complementary to the shape of the bore in the connection element in which it is inserted, which tail is provided with portions in relief of outline matching the outlines of the liquid transfer ports. 
     
     
         12 . The device according to  claim 1 , wherein the adaptor comprises a cylindrical body from which said head extends axially, a base mounted on an open end of the cylindrical body, and a sealing gasket slidable in the body under drive from an annular control element passing through the base and having a sealing rod that is inserted in the head in order to close the holes.
