Abstract

A fuel pump, including a case, including a first section including a hub and a hole, a second section circumferentially arranged around the first section, wherein a radial space is arranged between the first section and the second section, an inlet in fluid communication with the radial space, a housing chamber arranged adjacent to the first section, and an outlet in fluid communication with the hole, a filter bowl removably connected to the second section, the filter bowl fluidly connecting the radial space with the hole, a valve assembly arranged at least partially in the first section and at least partially in the housing chamber, and a coil operatively arranged to apply a magnetic field to the valve assembly to selectively displace fluid therethrough.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Articles 4 and 8 of the Paris Convention for the Protection of Industrial Property Stockholm Act of U.S. Provisional Patent Application No. 62 / 854,368, filed May 30, 2019, the entire contents of which are incorporated by reference into this article. technical field [0003] The present disclosure relates to fuel pumps, and more particularly, to solenoid actuated fuel pumps. Background technique [0004] Fuel pumps are often, but not always, an essential component of a car or other internal combustion engine equipment. Many engines (especially older motorcycle engines) don't need any fuel pumps at all, just gravity to feed fuel from the fuel tank or under high pressure to the fuel injection system. Typically, carbureted engines use a low-pressure mechanical pump mounted outside the fuel tank, while fuel-injected engines typically use an electric fuel pump mounted inside the tank ...
