<p>The proposed electrohydraulic apparatus consists of a compact body containing an electric motor (17) a pump and a hydraulic cylinder with hydraulic liquid (20), formed by a through external cylindrical jacket (1) with cooling ribs (2), a first superstructure (3) for connecting to a feeding network, a second superstructure (4) and a third superstructure (5) for the control, and an internal cylinder (6) being concentrically placed in the cylindrical jacket (1) at one end thereof. Inside the cylinder, (6) there is disposed a tightly and movably mounted piston (7) with a piston rod (8). The cylindrical jacket (1)is tightly closed from both sides by an upper lid (9) and a bottom lid (10). On the side, where the piston rod (8) projects from the body the upper lid (9) is provided with a guide hole (11) and a packing (12), while at the cylindrical jacket (1) opposite end the bottom lid (10) is provided from outside with an arrangement for outer attachment (13) of the apparatus body, whereby the axis of the attachment holes is perpendicular to the axis of the piston rod (8) and at the same time it is perpendicular to or parallel with an axis formed by sides provided with the cooling ribs (2). From inner side the bottom lid (10) is provided with a first reinforcement (14) for mounting a first bearing (15) of one end of the electric motor (17) and around the first reinforcement (14) there is arranged on the bottom lid (10) a hollow cylindrical body (18) with through-flow holes. In said hollow cylindrical body (18) there is fixedly fastened said electric motor (17) stator (36). At the electric motor (17) rotor (16) other end, there is arranged a rotor (19) of the hydraulic liquid (20) pump, which hydraulic liquid (20) is contained in the apparatus cavities. The pump rotor (19) is disposed at the same time in the pump body (21) that contains mounting of a second bearing (22) of the electric motor (17) rotor (16), and at the same time the pump body (21) outer edge (23) is seated in the internal cylinder (6).</p> |
