SUBSTANCE: claimed system comprises the controller and inertial transducer and earthmover working tool manual control connected therewith. The controller generates the signals of control over adjustable hydroelectric drive of working tool lift/drop and/or skew of the working tool proceeding from stabilisation of its angular position relative to earthmover or gravity vertical, the position in height relative to earthmover, soil surface or preset design surface, speed of displacement in a coordinate or ratio between horizontal and vertical displacement speeds. Additionally implemented are various options including combined manual and automatic control of the working tool, determination of its position or working parameters with the help of inertial transducers built around the accelerometers, gyros and digital processing of their signals, application of portable levelling device and transponders or RFID-markers for control over the initial level of soil surface, various methods of input and display of the data on design and actual soil surface, etc.

EFFECT: higher accuracy of earthmover operation, expanded applications.

SUBSTANCE: group of inventions relates to diffuser device and working machine with such device. Diffuser device comprises container for fluid medium connected with outlet tube and return tube for reverse flow, which enters container and forms first fluid medium outlet, having first outlet hole to discharge fluid medium from return tube. Device also includes second fluid medium outlet, at least partially surrounding said first outlet, and second output hole providing introduction of fluid medium from first outlet hole into container. Second outlet hole for fluid medium is made in second fluid medium outlet. Direction of second outlet hole differs from first outlet hole direction.

EFFECT: since fluid medium outlet hole direction in sleeve is different from outlet hole direction in return tube first part, fluid medium in diffuser device may stably come back into container without formation of bubbles.

On the ends of the shaft of outer and inner open gear rims of the toothed sleeve, there are annular blind bores of 3 mm width or more made on the depth of teeth bevels end value of diameters: greater than the diameter of hollows of the shaft outer rims and the sleeve, and less than the diameter of the hollows for the inner gear rim of the sleeve. The engagement of teeth when assembling the outer and inner rims of the toothed sleeve with mating toothed rims on drums is made at wide recesses between the teeth of external and internal rims made on toothed sleeve and the drum shaft by means of special modified tooth-cutting involute tool with reduced diameter of recesses. Cuts on the bevelled teeth are made, for example, by an electro erosion tool. The toothed sleeve is made of titanium alloy, for example, BT 20.
