Liquid transfer apparatus and adaptors

An adaptor for fitting to an aperture provided in a wall of a storage tank for receiving the spigot portion of liquid transfer apparatus as previously described, the adaptor including:

• a socket portion having an elongate passage extending therethrough with an entry at one end adapted to receive therethrough the spigot portion of the liquid transfer apparatus for sealing engagement in the passage, and an outlet at the other end for allowing liquid to flow out of said socket portion into the storage tank to which the adaptor is fitted;
• deflector means depending from said socket portion and extending across the passage for deflecting liquid sideways of said passage;
• closure means for selectively closing said entry;
• a flange extending outwardly from said socket portion intermediate said entry and said outlet and an external thread on a portion of said socket portion between said flange and said outlet, and
• a nut adapted for threaded engagement with said threaded portion, the parts being so made and arranged that the threaded portion may be passed through the aperture in the storage tank wall and the flange engaged against one face thereof while the nut engages against the other face to secure the adaptor to the storage tank wall.

An adaptor for fitting to an opening of a container and adapted to co-operate with a spigot portion or other part of a pump or other liquid transfer apparatus for filling the apparatus with liquid from the container, the adaptor including:

• a socket portion having an entry adapted to receive therethrough the spigot portion or other liquid entry part of the liquid transfer apparatus for sealing engagement of the spigot portion in said socket portion;
• and
• securing means on said socket portion or operatively connected to said socket portion for securing said socket portion to the container for liquid communication of the socket portion with the container via the container opening, and a liquid inlet in said socket portion for allowing liquid to flow into said socket portion from the container and a fluid outlet spaced from the fluid inlet which is connected to a fluid flow passage through which fluid can flow into the container and is adapted for sealed fluid communication with a complementary fluid outlet on the pump or other liquid transfer apparatus with which the adaptor is to be used, whereby air, vapour or other fluid expelled from the pump can flow through the fluid outlet and into the container thereby allowing the pump and the container to form a closed system during transfer of liquid from the container to the pump, said fluid flow passage opening within the bounds of the securing means so that fluid flowing therethrough will flow into the container via the container opening;
• said socket portion being formed as one component which is fitted within another component to provide therebetween the flow passage for fluid flow from the fluid outlet to the container;
• the parts being so made and arranged that liquid may flow from said socket portion to the liquid transfer apparatus though the spigot portion or other liquid entry part upon vacuum being thereto applied, the diameter of said entry being greater than the diameter of the opening of the container.
