    摘要： An air chuck (10) for facilitating the connection of a pneumatic hose with a threaded stem (70) of a tyre valve (12) includes a housing (20) with an air passage. The housing (20) includes an air inlet port connectable to the pneumatic hose, and an air outlet passage to receive the threaded stem of the tyre valve. A clamping member (36) is mounted externally about the outlet passage and includes a hollow tubular member, a front end portion of which terminates in a plurality of separate, radially deflectable fingers (38), a free end portion of each finger extending towards the discharge end of the outlet passage. The free end portions of each finger (38) define an aperture for receiving the threaded stem (70) of the tyre valve (12). The size of the aperture is variable by the movement of a sleeve (44), slidable over the body of the housing and the clamping member.

    摘要： The invention provides an apparatus comprising a grease gun (10) having a delivery line (22), the apparatus being configured to return grease under pressure from within the delivery line (22) of the grease gun (10) back to a grease reservoir (14); the grease gun (10) comprising a dispensing head (12) fitted to reservoir (14) containing grease and including a grease inlet port (16), for receiving grease from the grease reservoir (14), a grease outlet port (20) connectable to the delivery line (22) for dispensing grease; a pressure chamber (18) wherein the grease inlet port (16) is in fluid communication with the grease outlet port (20) via the pressure chamber (18); a piston (28) operable for displacing the grease from the grease inlet port (16) to the grease outlet port (20); and a one-way flow control valve located between the pressure chamber and the grease outlet port to inhibit the reverse flow of the grease from the grease outlet port back into the pressure chamber; the dispensing head (12) further comprising a pressure return port (26),located upstream of the grease inlet port (16) and linked to the grease outlet port (20) by a pressure return passage and openable into the pressure chamber (18), for returning the grease under pressure to the pressure chamber (18) and the grease reservoir (14), in which the piston (28) acts as a valve movable between a first position where the pressure return port (26) is closed and a second position where the pressure return port (26) is open.
