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 ).
