<p>An oscillating armature pump for liquids operated by alternating current and having a housing defining a pump cavity, with a. c. coils mounted laterally of the cavity on a block. The oscillating armature is mounted on a plate spring which is secured to the pump housing, and the armature is also provided with a resiliently flexible plate for executing the pumping movement. The plate spring is substantially U- or Omega-shaped, so that it takes up a minimum space, and also provides a favorable transition between the active oscillating end of the spring plate and the static end of the plate secured to the housing.</p> |
