Problems solved by technology

Some deflectors are usually formed from one piece of flat material that is "C" shaped and therefore do not completely surround the components it is adjacent to and therefore do not completely direct the airflow, or they are formed from multiple pieces, requiring more components and manipulations in the combination , then the cost and time of assembly increases, and when one or more pieces are missing or installed incorrectly, the potential for incorrect or incomplete assembly increases

Embodiment Construction

[0025] Referring to the figure above, especially the figure 1 With 2, there can be seen a paint pump device 20 suitable for use in the practice of the present invention. Apparatus 20 is intended to pump paint and similar coating materials at high pressure to a paint spray gun (not shown) for application by vacuum spraying to the surface to be coated.

[0026] Apparatus 20 includes paint reservoir 22 and pump assembly 24 carried by frame 26 . The reservoir 22 may have a cover 28 . The frame 26 preferably has a handle portion 30 and a pair of foot portions 32,34. Footing portions 32 and 34 are received in a base 36 that supports pump unit 24 . It should be understood that after the top cover 40 is removed, a high pressure hose (not shown) is connected to the outlet 38 of the pump unit 24 . The high pressure hose may also be connected to a vacuum spray gun (not shown) to deliver paint or other coating material to the surface to be coated (not shown). The inlet 42 of the pump...

Abstract

An improved cooling arrangement for an electric motor in a pump assembly, including a resilient fan baffle having a planar main surface and a pair of wings extending perpendicularly out from the main surface to direct airflow away from the motor when the fan baffle is installed on the motor. A method of installing the fan baffle includes bending two ends of the periphery of the fan baffle to clear obstructions on the motor, and then releasing the ends to allow them to come together in a planar arrangement.

Description

[0001] Cross-References to Cross-Applications [0002] Reference is made herein to the following co-pending and commonly assigned U.S. patent applications by the same inventor, each of which was filed on the same date as the present application, and each of which is expressly incorporated herein by reference: [0003] i) Filter and valve release, serial number ___________; and [0004] ii) Modified swash plate pump, serial number _________. technical field [0005] This invention relates to the field of pumps for paint and related coating materials, and more particularly to electric motor driven pumps for such applications. Background technique [0006] In the past, we have known to provide sheet metal and other baffles and structures to direct air in electric motor driven equipment. Some deflectors are usually formed from one piece of flat material that is "C" shaped and therefore do not completely surround the components it is adjacent to and therefore do not completely ...
