Abstract
A linear pump has a housing containing a cylinder and piston arrangement and a motor with a slotted stator containing a wire coil driving an armature connected to the piston to reciprocate the piston within the cylinder along a piston axis. The housing defines a pair of straight air intake vent tubes in communication with ambient air and extending to proximate the motor. The vent tubes serve to provide both the primary breathing passages of the pump as well as cooling passages for the motor.
