Solenoid actuated flow control valve including adjustable spacer

A fueling system for an internal combustion engine comprising:

• a plurality of valve actuator assemblies;
• each of the valve actuation assemblies further comprising:
• a stator assembly;
• an armature housing;
• and
• an adjustable spacer coupled between the stator assembly and the armature housing, wherein the spacer compresses at a controlled rate when an axial load is applied thereto.

A method for adjusting a valve stroke in a valve actuator assembly, the valve actuator assembly comprising a stator assembly and an armature housing;

• the method comprising:
• providing an adjustable spacer between the stator assembly and the armature housing;
• assembling the valve at a high nominal stroke;
• and
• compressing the adjustable spacer at a controlled rate to control the valve stroke to meet performance requirements.

A valve actuator assembly comprising:

• a stator assembly;
• an armature housing;
• an adjustable spacer coupled between the stator assembly and the armature housing, wherein the spacer compresses at a controlled rate when an axial load is applied thereto;
• wherein the adjustable spacer comprises a ring shaped member, the ring shaped member including a plurality of raised pads thereon;
• a ball valve;
• and
• a seat for the ball valve, wherein the compression of the adjustable spacer allows for the adjustment of a gap between the ball valve and the seat to control the valve stroke.
