Patent number: 11519497Abstract: Embodiments of the present disclosure provide a transmission spool valve/valve body arrangement facilitating the manufacturing of the valve body chambers accommodating the spool valves. Specifically, embodiments of the present disclosure provides a valve body having a common datum from which machining for each valve cavity formed through a particular face of a valve body can be referenced. In particular embodiments of the disclosure, a spring biases a solenoid assembly for each valve against a datum (common or otherwise). In more particular embodiments of the disclosure, the spring biases the solenoid assembly in a direction opposite to the direction of actuation of the spool valve upon actuation of the solenoid assembly. The spring bias positively displaces the solenoid assembly to the datum for precision location of the solenoid relative to the various hydraulic ports of the respective valve chamber. A variety of spring clip arrangements are provided to index the solenoid to the valve body.Type: GrantFiled: December 6, 2018Date of Patent: December 6, 2022Assignee: Allison Transmission, Inc.Inventors: Elizabeth P.
