Foam pump

A foam pump comprising a fluid cylinder, an air cylinder and a mixing chamber, in which the mixing chamber comprises a fluid throughflow axis, a fluid inlet and an air inlet, in which the fluid cylinder and the air cylinder both comprise a stroke axis which is arranged at substantially 90 degrees to said fluid throughflow axis, namely, in a range of 15 degrees either side of 90 degrees thereto, 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 through said fluid inlet 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 through said air inlet in a dispensing stroke, in which said fluid inlet faces in a fluid flow direction of the mixing chamber, and in which said air inlet is arranged downstream of said fluid inlet and faces in substantially the opposite direction against said fluid flow direction.
