Abstract
Disclosed is an adaptor for connecting a grease injection gun to either of a lipped or a threaded grease cartridge; the adaptor including a tubular sleeve, having an internal diameter slightly larger than the external diameter of the grease cartridge, but smaller than the lip of the lipped cartridge, for receiving the discharge end portion of the cartridge; and an adaptor head shaped and dimensioned to form a closure over the tubular sleeve, the adaptor head including an outer face configured to releasably connect with the grease injection gun, and an inner face shaped and configured to releasably connect with the tubular sleeve and the cartridge, with a flow passage extending between the outer face and the inner face, for fluid communication between the grease injection gun and the cartridge.
Claims10
An adaptor (40) for selectively connecting a grease injection gun (10) to each of a lipped (30) grease cartridge and a threaded (31) grease cartridge, the adaptor (10) comprising:
- a tubular sleeve (42),
- the tubular sleeve (42) having an internal diameter larger than an external diameter of the grease cartridge (30,31) but smaller than a lip of the lipped grease cartridge (30), the tubular sleeve for receiving a discharge end portion of the cartridge;
- and
- an adaptor head (44) shaped and dimensioned to form a closure over the tubular sleeve (42),
- the adaptor head (44) comprising an outer face configured to releasably connect with the grease injection gun (10), an inner face configured to releasably connect with the tubular sleeve (42) and the grease cartridge (30, 31), and a flow passage (56) extending between the outer face and the inner face, the flow passage (56) for fluid communication between the grease injection gun (10) and the grease cartridge (30,31),
- the inner face of the adaptor head (44) having a base with a first internally threaded recess (46) dimensioned to receive the lip of the lipped cartridge and dimensioned to receive a complementary externally threaded portion (48) of the tubular sleeve (42) in a screw threaded connection,
- the adaptor head (44) further comprising a second threaded recess (54) complimentary in diameter to a threaded outlet (34) of the threaded grease cartridge (31), the second threaded recess (54) being concentrically located in the base with the first recess (46) and in communication with the flow passage (56),
- wherein the flow passage (56) terminates in an outlet pipe (58), the outlet pipe (58) being smaller in diameter than an inlet port (20) of the grease injection gun (10), extending from the outer face of the adaptor head (44), and
- wherein the outlet pipe (58) of the adaptor head (44) is receivable in the inlet port (20) of the grease injection gun (10) and releasably connected by a screw threaded connection.
An adaptor (40) for connecting a grease injection gun (10) to a grease cartridge (30, 31), the adaptor (10) comprising:
- a tubular sleeve (42) for receiving a discharge end portion of the cartridge, the tubular sleeve (42) having an internal diameter;
- and
- an adaptor head (44) shaped and dimensioned to form a closure over the tubular sleeve (42),
- the adaptor head (44) comprising an outer face configured to releasably connect with the grease injection gun (10), an inner face configured to releasably connect with the tubular sleeve (42) and the grease cartridge (30, 31), and a flow passage (56) extending between the outer face and the inner face, the flow passage (56) for fluid communication between the grease injection gun (10) and the grease cartridge (30,31),
- the inner face of the adaptor head (44) having a base with an internally threaded first recess (46) of a first size dimensioned to receive a complementary externally threaded portion (48) of the tubular sleeve (42) in a screw threaded connection,
- the adaptor head (44) further comprising an internally threaded second recess (54) of a second size, an inside diameter of the second recess (54) being smaller than an inside diameter of the tubular sleeve (42), the second recess (54) being concentrically located in the base having the first recess (46) and in communication with the flow passage (56),
- wherein the flow passage (56) terminates in an outlet pipe (58), the outlet pipe (58) being smaller in diameter than an inlet port (20) of the grease injection gun (10), extending from the outer face of the adaptor head (44), and
- wherein the outlet pipe (58) of the adaptor head (44) is receivable in the inlet port (20) of the grease injection gun (10) and releasably connected by a screw threaded connection.
