摘要:
An electro-hydraulic control mechanism for use with a multi-speed transmission includes a pair of logic valves, which are manipulated during the ratio interchanges and the ratio establishment by aiding in the distribution of fluid pressure from a plurality of trim valves. A diagnostic valve is incorporated into the hydraulic system, which controls the pressure of a diagnostic switch between an on state and an off state. The position of this diagnostic switch provides an indication of the operating condition or lack thereof in a power transmission.

The present invention provides a method and apparatus for a self-cleaning valve assembly. The valve is adapted to cycle and thereby clean the valve assembly in response to one or more predefined parameters which are programmed into a programmable controller. The valve is additionally configured to cycle according to one or more of several different methods which have been shown to efficiently clean the valve assembly. In this manner, the valve assembly is automatically cleaned improving the efficiency thereof and eliminating stuck valve warranty returns.

A portable pressure washer includes a housing having a front end and a rear end defining a longitudinal axis. A handle has a first end extending from a rear portion of the housing and a second end terminating in a barrel. A first nozzle and a second aperture extend from the barrel. A fluid pump and a motor disposed are disposed within the housing, which includes a fluid inlet in fluid communication with the first nozzle and the second aperture.

A powertrain has an electrically variable hybrid transmission having an electro-hydraulic control system, plurality of electrical power units, and a plurality of torque transmitting mechanisms selectively engageable by the electro-hydraulic control system to provide four forward speed ranges, a neutral condition, an electric low and high speed mode, and an electrically variable low and high speed mode. Additionally, the electrically variable hybrid transmission provides a parallel reverse mode and a series reverse mode. The present invention provides an improved electro-hydraulic control system having a multiplexed electronic transmission range selection (ETRS) and reverse dog clutch system for an electrically variable hybrid transmission. The multiplexed control system of the present invention allows effective control of both the ETRS system and reverse dog clutch system using only one solenoid valve.

A power washer is provided with a transport frame, a wash unit and a gun. The wash unit and the gun may be separated from the transport frame to be used in multiple modes. Possible modes include a walk-behind mode, a spray mode and hand wash modes. A quick connection is also provided to make it easier to disconnect and reconnect various components of the power washer.

The present invention provides a multiplexed control system, employing a single solenoid valve, to selectively control the damper lock-out clutch and motor/generator cooling of an electronically variable hybrid transmission. The present invention also contemplates a method of selectively controlling damper lock-out clutch engagement and motor/generator cooling for an electrically variable hybrid transmission control.

A laser leveling device having a suction mounting arrangement includes a housing and a mounting seal extending from the lower portion of the housing. The mounting seal cooperates with an attachment surface to define a suction mounting area therebetween. The suction mounting arrangement cooperates with the mounting seal to maintain the vacuum pressure seal in the suction mounting area. A laser light source mounted within the housing in a planar relationship relative to the attachment surface includes at least one diode projecting an alignment beam through an opening in the housing to denote a reference plane along the attachment surface.

A fuel powered machine having an engine with an output shaft that extends substantially downward from the engine. The output shaft is rotationally connected with a working member that is located substantially below the engine. A frame rigidly supports the engine and the working member and all are enclosed within an internal volume formed by a housing that includes at least one panel that is mounted to the frame. The panel includes at least one aperture that is suitable for air flow through the apertures and past the engine and the working member. Operational controls are positioned on one of the plurality of panels for controlling the operation of the fuel powered machine, and an output connector provided through one of the plurality of panels.

Provided is an apparatus to enable a torque transmitting mechanism within an automatically shiftable power transmission to disengage at vehicle stop such that the slip within a fluid drive device is reduced. When vehicle movement is required a main pressure regulator trims the torque transmitting mechanism into engagement. A method of reducing engine load at vehicle stop by employing the apparatus of the present invention is also provided.

A modular tool assembly including a tool base configured to releasably secure a modular tool arrangement in a fixed relationship relative to a mounting surface. The tool base includes an upper housing portion and a lower housing portion having a mounting seal extending therefrom. The mounting seal cooperates with the mounting surface to define a vacuum pocket therebetween. A vacuum generating mechanism is configured to remove air from the vacuum pocket through an aperture in the lower housing portion. A modular tool attachment releasably engages a portion of the tool base to secure the modular tool attachment to the tool base. The modular tool attachment can include a self leveling laser leveling device having a laser light source mounted within a housing to project an alignment beam through an opening in the housing to denote a reference plane along the mounting surface.
