Abstract: A pressure washer system includes an engine block, a water conduit, a water pump, and a spray gun. The engine block is for a horizontally-shafted internal combustion engine, and has a chamber therein. The chamber is designed to contain oil for cooling and lubricating the internal combustion engine. The water conduit has a garden hose connector on an end thereof, and is fastened to the engine block. As such, heat transfers from the engine block to a flow of water passing through the water conduit during operation of the internal combustion engine. The water pump is coupled to the water conduit, where the flow of water is driven by the water pump. The spray gun is coupled to the water pump, where the flow of water exits the pressure washer system via the spray gun.

Abstract: A pressure washer system includes an internal combustion engine and a water pump. The internal combustion engine includes an engine block forming a chamber and a cover for the chamber. The cover has an area designed to hold a lubricant. Additionally, the engine includes a crankshaft within the chamber. The water pump includes a pumping mechanism, an inlet, an outlet, and a fluid passage. The pumping mechanism is powered by the crankshaft. Water enters the pump through the inlet and exits the pump through the outlet. The fluid passage extends between the inlet and the outlet. A portion of the fluid passage is formed in the cover of the engine. Heat transfers from the lubricant of the engine to the water of the water pump during operation of the pressure washer system.

Abstract: A method for a communication device for establishing a secure authenticated channel using multiple shared keys traded with another device is described. A first shared key common to a home domain is received from a non-device entity, such as a domain manager or a trusted third party. Also, a second shared key is established with the other device. An initial integrity protection of communication relating to rights sharing between the communication device and the other device is then created using the second shared key. The integrity protection of communication relating to rights sharing between the communication device and the other device is thereafter augmented using the first shared key.

Abstract: The centrifugally-responsive compression release apparatus of the present invention is a compact unit which can be simply snap-fit to a position on the cam shaft during assembly and will retain that position during engine operation. The compression release apparatus relieves compression in at least one chamber of an internal combustion engine by utilizing a lift member engageable with a valve operating device and centrifugally-responsive means for changing the position of the lift member in response to engine speeds. The apparatus includes a base member which can be injection molded to a shape of a segmented cylinder thereby substantially corresponding to the shape of the outer surface of the cam shaft. The base member also provides means for integrating and retaining the dynamic components of the apparatus to the base member.
