Ball check valve assembly for vehicle powertrain hydraulic control units in which the length of web portion restricts one spherical element from sealing the respective opening when the other spherical element seals its respective opening

摘要

A dual check ball (106) has two spherical elements (108,110), where each seals an inlet opening (114,116) defined in a valve housing (101). The dual check ball also has a central web portion (112) that attaches the spherical elements together. The length of the web portion restricts one spherical element from sealing the respective opening when the other spherical element is sealing its respective opening.
