Abstract (en)
A vapour recovery pump for a fuel dispensing unit comprises a pump housing (2) with a first chamber (3) and a second chamber (4), each chamber (3, 4) having a vapour inlet valve and a vapour outlet valve, respectively. The chambers (3, 4) are separated by a movable piston (9) arranged to repeatedly decrease and increase the volumes of the chambers (3, 4). The piston (9) comprises a magnetic device (11), and electromagnetic control means (14) are configured to move the piston (9) by altering a magnetic field, for repeatedly decreasing and increasing the volume of the chambers (3, 4).
