Abstract
A check ball valve cartridge assembly is provided for regulating fluid flow through a fluid pressure line in an automotive transmission. The assembly includes a cartridge having a side wall forming a hollow interior cavity in the cartridge and a lip extending from the side wall toward a central axis of the cartridge. The assembly also has a check ball, which is disposed at least partially within the interior cavity of the cartridge. The lip of the cartridge is configured to prevent the check ball from exiting the interior cavity of the cartridge. A biasing member is disposed at least partially within the interior cavity of the cartridge and contacts the check ball. The assembly may include a pair of orientation features extending from the side wall of the cartridge for aligning the cartridge for installation within the automotive transmission.
