| 20100202901 | SELF LUBRICATING PUMP - A self-lubricating water-cooled piston-style water pump has a unitary pump housing with a crankcase in direct water communication with the water pump inlet. A low pressure chamber is in direct water communication with the crankcase. A compression chamber is in direct pressurized water communication with a high pressure water manifold through a one-way valve. A high pressure water pump outlet extends outwardly from the manifold to the exterior of the housing. A crankshaft is connected to a connecting rod and a plunger rod, both of which are lubricated and water-cooled in the crankcase. A compression plunger has water channels therethrough connected to the plunger rod and in water communication with the low pressure chamber. The plunger is reciprocal within the compression chamber. A second one-way valve is on the plunger in the compression chamber to let water into the compression chamber. | 08-12-2010 |
| 20080199245 | Window cleaning apparatus with deionization cartridge - The invention, an apparatus for cleaning surfaces such as windows, connects to a water source, and uses a portable cylindrical deionized water unit, a garden hose, a replaceable ion exchange resin cartridge, a brush pole system, and a second hose. The cylindrical deionized water unit has an inlet opening, an outlet opening, first and second separate interior chambers; and a valve with first and second positions. The valve at the first position directs water flow through the inlet opening into the first chamber and out through the outlet opening. The valve at the second position directs the water flow through the second chamber and out through the outlet opening. A garden hose connects the inlet opening to the water source. A replaceable ion exchange resin cartridge fits into the second chamber. The brush pole system uses: a hollow pole with an inlet portal, an outlet portal, and a brush. A second hose with a first end that connects to the outlet opening of the cylindrical deionized water unit; and the second hose with a second end connects to the inlet portal of the hollow pole. | 08-21-2008 |
