Electronic coolant valve with integral actuator mechanism

摘要

An electronic coolant valve mechanism with an integral actuator mechanism. The coolant valve mechanism utilizes an electric motor and a planetary roller mechanism integrated into a valve body to translate and operate a valve member in a linear direction. A manifold can include a plurality of coolant valve mechanism operating independently by a control system.

1. A valve mechanism comprises:
(a) a manifold; (b) a plurality of coolant valves positioned in said manifold; (c) each of said coolant valves comprising: (i) a housing member;
(ii) a valve member having a head member and a stem member, said stem member positioned in said housing member and having threads thereon;(iii) an electric motor;(iv) a planetary roller mechanism positioned in said housing member, said planetary roller mechanism having a roller housing member and a plurality of threaded roller members rotatably positioned in said roller housing member;(v) wherein activation of said motor causes said rotor rotates said roller housing member and said roller members to rotate, which in turn cause said valve member to translate in an axial direction relative to said housing member.
