Abstract
A nebulizer pump includes an axial cylinder and piston arrangement and an electromagnet having a stator and an armature that drives the piston to reciprocate within the cylinder. The pump housing has a unitary partition defining an exhaust chamber in combination with the valve head that isolates air at the intake port from air at the exhaust port. The entire assembly can be clamped together by the housing or clamped separately and isolated from the housing by coil springs.
