Patent ID: 6913242

Claim:
In a solenoid plunger system for an electro-pneumatic pressure transducer, said plunger system comprising elements being at least partially arranged in a cladding, said elements including a solenoid plunger, a core selected from an iron core and a magnetic core, at least one recess selected from a first recess in the solenoid plunger for receiving the core and a second recess in the core for receiving an end of the solenoid plunger, an air gap between the cladding, the solenoid plunger and the core, said air gap being adjustable by relative movement between the solenoid plunger and the core while one of the solenoid plungers is partially movable in and out of the second recess and the core is movable in and out of the first recess, and the core being movable relative to the solenoid plunger for setting the air gap, the improvements comprising a threaded sleeve by which the core is movable relative to the solenoid plunger, a spacer between the cladding and the threaded sleeve, and a damping element being received in said at least one recess.
