    摘要： Apparatus and associated methods relate to remote priming of a texture sprayer. The texture sprayer includes a main unit, a hose assembly and a spray gun, the main unit includes an air compressor, a sensor that senses a parameter of air compressed by the air compressor, and a texture material pump that is activated and deactivated in response to the parameter sensed. A spray gun can be remoted coupled to the main unit via the hose assembly. The spray gun includes a nozzle, from which the texture material is forcefully expelled as a spray, a trigger, and a prime valve. Actuation of the trigger causes the spray gun to mix the compressed air with the texture material and to forcefully expel the texture material as a spray from the nozzle, thereby causing flow of the compressed air. Opening the prime valve releases the compressed air thereby causing flow of the compressed air.

    摘要： A method for the weight-dependent control of the internal pressure of a supporting body loaded by a weight load or payload, wherein the internal pressure is produced by means of an electric-motor-driven compressor, and the weight load or payload which is present and which acts on a supporting body in the form of a mass mLoad under the effect of acceleration due to gravity g is determined in that a reduction and a subsequent increase in the internal pressure take place, wherein the increase in the internal pressure causes the position of an application point of the weight load or payload to change by a position difference ΔZ, wherein:



    during the increasing of the internal pressure by means of the compressor, the motor current ILoad of the drive motor of the compressor is measured with a constant motor voltage U and integrated over the time of the increase in pressure, and the electrical work WLoad which is necessary for the change in position is determined therefrom,
    wherein the electrical work WLoad the electrical work WLoad is compared with a characteristic value of the electrical work W0 from a characteristic diagram, wherein the change in position ΔZ, the difference in mass Δm and the difference in payload ΔFZ are determined from the difference ΔW between WLoad and W0 and the mass mLoad and the weight load or payload which is actually present as a result is determined therefrom.

    摘要： A portable, refrigerant recovery unit for transferring refrigerant from a refrigeration system to a storage tank. The recovery unit includes two, opposed piston heads rigidly attached to respective piston rods that extend along a common fixed axis. The piston rods are rigidly attached to the yoke member of a scotch yoke arrangement. In operation, incoming refrigerant from the system is simultaneously and continuously directed to the opposing piston heads wherein the forces of the pressurized refrigerant on them counterbalance or neutralize one another. The recovery unit also has a cooling fan driven by the motor for driving the scotch yoke in which the fan is driven through a step up gearing arrangement. In operation, the drive shaft of the motor is rotated at a first rate and the driven shaft of the fan is driven at a greater rate (e.g., twice the first rate) by the step up gearing arrangement.
