FOAM PUMP

摘要

A-foam pump (1) comprising a fluid cylinder (2), an air cylinder (3), and a mixing chamber (4), in which the fluid cylinder is adapted to draw a fluid therein in a priming stroke, and to pump said fluid into said mixing chamber in a dispensing stroke, in which the air cylinder is adapted to draw air therein in a priming stroke, and to pump said air into said mixing chamber in a dispensing stroke, in which the mixing chamber comprises a fluid throughflow axis (A-A), in which the fluid cylinder and the air cylinder are co-axial with one another and are aligned on a second axis (B-B) which is substantially normal to said fluid throughflow axis, in which the fluid cylinder and the air cylinder are provided with a common piston member (5), and in which the foam pump comprises spring means (6) adapted to bias said common piston member to perform a priming stroke of the fluid cylinder and the air cylinder.
