Abstract:
A foam dispenser has a pump body and a sprung plunger ( 2 ). A one-piece moulded cylinder component ( 31 ) comprises a larger diameter portion ( 32 ) for an air cylinder and a smaller diameter portion ( 33 ) for a liquid cylinder. The plunger ( 2 ) carries respective pistons ( 22,21 ) movable in the air cylinder and liquid cylinder to pump air and liquid through valved outlets to a mixing chamber ( 8 ) in the plunger for foam production. The liquid cylinder has a discrete inlet piece ( 9 ) including an inlet valve. The liquid outlet valve is operated by a valve pin ( 25 ) connected to a valve pin retainer ( 39 ) which is formed integrally as a one-piece moulding with the cylinder component ( 31 ).

Claim (Index 13):
Foam dispenser comprising:\n a pump body, a pump plunger reciprocable relative to the pump body and a pump spring biasing the pump plunger towards an extended position relative to the pump body; wherein the pump body has an air cylinder defining an air chamber and a liquid cylinder defining a liquid chamber, and an inlet portion including an inlet valve and being for receiving liquid into the liquid cylinder from a container of liquid to be foamed, and wherein the pump plunger has an air piston movable in the air cylinder to vary the volume of the air chamber and a liquid piston movable in the liquid cylinder to vary the volume of the liquid chamber; wherein a mixing chamber being defined in the pump plunger for mixing air and liquid under turbulent conditions to form foam, one or more air outlets leading from the air chamber to the mixing chamber and one and more liquid outlets leading from the liquid chamber to the mixing chamber via a liquid outlet valve; and wherein the liquid outlet valve is operated by a valve pin connected to a valve pin retainer in the liquid chamber downstream of the inlet valve, and the pump spring is positioned in the air chamber.
