Abstract: Power unit (101) comprising: a tank (104) for hydraulic oil; an electric motor (105); a power pack body (102) inside of which a hydraulic circuit extends; a hydraulic pump (103) integrated in a cavity (102a) of the power pack body (102).

Abstract: The valve assembly of the invention comprises a one-piece body (10) having in its interior a single main axial cylindrical cavity (11) of rectilinear axis, communicating via an outer mouth with at least one outer face (10a) of the one-piece body (10), and first channels (13, 14, 14′, 15) communicating with said main cavity (11) and connected to the delivery side (13) of a liquid pressurizing pump, to the discharge, and to at least one user take-off (16) respectively; inserted into the one-piece body (10), a cylindrical cartridge (20) having an axial second cavity (21) coaxial with the main cavity (11), which cartridge engages the surface of the main cavity (11) and is arranged to create, between its own cylindrical outer surface and the surface of the main cavity (11), passages providing communication between said first channels (13, 14, 14′, 15); valve elements (E1-E4), inserted into the second cavity (21) and arranged to define, in combination with this latter, at least two or more valves with d

Abstract: The valve comprises a slider-valving member having two lateral valving elements (22, 22A, 22B) positioned on one and the other side of the transverse central plane, they being subjected to the direct action of thrust means (15) and movable axially between a first operative position defining said normal configuration of the slider-valving member (20, 20A, 20B), and a second operative position in which a further different communication condition between the channels is determined; spring means (23, 35, 45) are also provided, arranged to normally maintain the two lateral valving elements (22, 22A, 22B) in said first operative position.
