Publication number: 20120244013Abstract: An electromagnetic pump includes a cylinder with a stepped inner diameter with first and second inner diameters. A piston inside the cylinder, with a stepped outer diameter including first and second outer diameters slidable on the respective inner diameters, defines first and second fluid chambers. Reciprocal movement of the piston produces a greater change in volume in the first chamber than the second chamber. An electromagnetic portion moves the piston to decrease the volume of the first chamber and increase the volume of the second chamber. A biasing member moves the piston to increase the volume of the first chamber and decrease the volume of the second chamber. A first valve allows fluid to flow to the first chamber and prohibits reverse flow. A second valve embedded in the piston allows fluid to flow from the first chamber to the second chamber and prohibits reverse flow.Type: ApplicationFiled: March 6, 2012Publication date: September 27, 2012Applicant: AISIN AW CO., LTD.Inventors: Masaya NAKAI, Kazuhiko KATO
