Elastic support members for an electric actuator
First Claim
1. An electric actuator comprisinga housing,a permanent magnet disposed within said housing,an axially movable armature disposed within said housing,an actuating coil supported by said housing for driving said armature to axially move, andan axially moveable actuating rod fixedly connected to said armature, wherein said electric actuator further comprisesa pair of elastic support members having radially inner end portions fixedly connected to said actuating rod at opposite portions thereof adjacent said armature and radially outer end portions fixedly connected to said housing, respectively, each of said elastic support members consisting of a plurality of thin leaves laminated one upon the other, each of said elastic support members being formed with a plurality of arm portions equiangularly spaced apart with respect to one another and radially extending between said radially inner and outer end portions and a plurality of generally triangular openings each disposed between two adjacent arm portions, each of said arm portions being axially deflected with respect to said radially inner and outer end portions of said elastic support member.
