Abstract
A full admission pitot pump is described including a rotatable outer housing having at least a first rotor housing member and at least a first stator housing member secured thereto. The rotor housing member has a reduced diameter portion at its first end and an enlarged diameter portion at its second end. The stator housing member has an enlarged diameter portion at its first end which is secured to the enlarged diameter portion of the first rotor housing member. A stator is positioned within the housing and remains stationary as the outer housing is rotated. The first rotor housing member rotates with a housing and defines a plurality of spaced-apart passageways formed therein which communicate with a plurality of spaced-apart passageways formed in the stator. The medium to be pumped or compressed is supplied to the first end of a rotating rotor housing member with the vane members in the rotor housing member causing the medium to be centrifugally spun outwardly and supplied to the passageways in the stator housing member. The relationship of the outer housing, rotor and stator permits the pitot principle to be employed for efficient kinetic energy conversion to pressure.
