Abstract

A solenoid has an axially movable plunger having a plunger rod extending from it. The plunger rod has the capability of angular deflection relative to the axial movement of the plunger within the solenoid.

Claims

AMENDED CLAIMS [received by the International Bureau on 12 June 1995 (12.06.95); original claims 1, 11 and 13 amended; remaining claims unchanged (2 pages)]
1. A solenoid comprising:
a cylindrical portion of a bobbin defining a longitudinal axis;
a solenoid coil arranged around said bobbin;
a generally cylindrical plunger having an internal cavity, said plunger disposed within said bobbin and axially slidable therein;
a plunger rod disposed within said cavity of said cylindrical plunger, said cavity allowing conical angular movement of said plunger rod with respect to said longitudinal axis; and
an end cap having an aperture through which a stem of said plunger rod extends, said aperture having a lateral dimension at least twice as large as that of said stem coinciding therewith.
2. The solenoid according to Claim 1 further comprising a biasing member for urging said plunger in a specified direction.
3. The solenoid according to Claim 2 wherein said biasing member urges said plunger rod in said specified direction.
4. The solenoid according to Claim 1 further comprising a stop disposed at a first end of said guide tube.
5. The solenoid according to Claim 4 further comprising a biasing member disposed between said stop and said plunger for urging said plunger away from said stop.
6. The solenoid according to Claim 5 wherein said biasing member urges said plunger rod away from said stop.
7. The solenoid according to Claim 1 wherein said plunger includes a flange disposed at one end of said plunger, said flange extending radially inward from an interior surface of said plunger, said flange defining a first aperture.
8. The solenoid according to Claim 7 wherein said plunger rod includes a stem and a head, said head being axially slidable within said cavity of said plunger, said stem extending through said aperture defined by said flange.
9. The solenoid according to Claim 8 further comprising a stop disposed at a first end of said guide tube.
10, The solenoid according to Claim 9 further comprising a biasing member disposed between said stop and said plunger rod for urging said plunger rod away from
11. A solenoid comprising:
a housing defining an internal cavity having a closed end and an open end; a cylindrical guide tube disposed within said internal cavity and defining a longitudinal axis;
a solenoid coil arranged around said guide tube;
a generally cylindrical plunger having an internal cavity, said plunger disposed within said guide tube and axially slidable therein;
a plunger rod disposed within said cavity of said cylindrical plunger, said cavity allowing angular movement of said plunger rod with respect to said longitudinal axis of said guide tube; and
a stop disposed at a first end of said guide tube, said stop having a generally conical portion insertable within a mating generally conical portion of said internal cavity of said plunger.
12. The solenoid according to Claim 11 further comprising a biasing member for urging said plunger rod away from said stop.
13. The solenoid according to Claim 11 further comprising an end cap disposed at said open end of said housing, said end cap defining a first aperture, said plunger rod extending through said first aperture in said end cap, said first aperture including a generally conical surface which provides clearance for said plunger rod when said plunger rod is at an angle relative to said longitudinal axis.
14. The solenoid according to Claim 11 wherein said plunger includes a flange disposed at one end of said plunger, said flange extending radially inward from an interior surface of said plunger, said flange defining a second aperture, said plunger rod extending through said second aperture.
15. The solenoid according to Claim 14 wherein said second aperture includes a generally conical surface which provides clearance for said plunger rod when said plunger rod is at an angle with respect to said longitudinal axis.
