ABSTRACT:
Combined vapor pump and a liquid driven motor for driving same. A combined motor and pump, as aforesaid, is provided as a compact unit which is of sufficiently simple design, and possessed of sufficiently few parts, as to be economical in manufacture while being effective in operation and capable of long life with a minimum of maintenance. The unit is made in three basic components, namely a motor component, a pump component and a conduit component positioned between the motor and pump components whereby the manufacture and assembly of said components may be carried out quickly and efficiently and whereby, further, a malfunctioning unit can be quickly and easily repaired by replacing in a simple manner the malfunctioning component thereof. Means comprising a chamfer in the body structure adjacent the vanes of the motor are provided to minimize the deleterious effect of dirt or grit entering into the motor from the liquid used for driving same.
