    Abstract: A rotary expansible chamber device, as a compressor or an expander, comprising a housing having an interior surface and defining an inlet and an outlet, a shaft defining an axis of rotation and being supported in the housing, a rotor mounted within said housing and on said shaft, forming a preferably circular circumference and having a plurality of sealing vanes supported on the rotor to move radially to and from a retracted condition and an extended condition, wherein said interior surface and said circumference radially define a compressor or expander chamber extending from said inlet to said outlet and defining a maximum radial gap between said interior surface and said circumference, and a bypass chamber extending from said inlet to said outlet and defining a minimum radial gap between said interior surface and the circumference of said rotor, characterized in that a dynamic seal is positioned in the bypass chamber such that a fluid is prevented to short cut from a high pressure side to a low pressure side via said bypass chamber.

    Abstract: A vane-type fluid transmission apparatus includes a rotor eccentrically located in the room of a stator and the outer periphery of the rotor is tangent to the inner periphery of the room. At least one blade is pivotably connected to stator and movably inserted in at least one slot of the rotor. The distal end of the at least one blade is in contact with the inner periphery of the room so as to form a space for receiving fluid between the outer periphery of the rotor and the inner periphery of the room. The contact between the at least one blade and the inner periphery of the room increases the efficiency for transmitting fluid which enters into the stator from an inlet and leaves from the stator from an outlet.

    Abstract: A rotary machine (1) in the form of an expander is shown. The Expander Induces a housing (5) having a cavity (9), inlet and outlet ducts (11, 12) communicating with the cavity (9), a rotor (2) having a rotor axis (A), a number of vanes (15a, 15b, 15c) movably received in respective grooves (18) in the rotor (2) and articulately connected about an axis (C) to one end of a control arm (14a, 14b, 14c) and in the other end rotatable supported in a fixed shaft (24) extending centrally through the cavity (9) in the housing (5), and at least one working chamber (9a) which is part of the cavity (9), The housing (5) includes an internally cylindrical intermediate part (5c), which part interact with the rotor (2) and the vanes (15a, 15b, 15c). The rotor (2) forms a reel configuration having respective radially extending flange portions (2a', 2b') which are rotatable together with the vanes, and against which the respective end surfaces of the vanes act.

    Abstract: A rotary pump (1) is described for the continuous filling of mincemeat and the like, comprising a stator (2) with a cylindrical cavity, a closing cover (10) for the cavity of the stator (2), and a rotor (5) coaxially housed inside said stator (2) and revolving around its axis. The rotor (5) is made up of a central cylindrical portion (6) which extends along the axis and of a peripheral cylindrical portion (7) of such height that between said stator (2), said cover (10) and said rotor (5) is defined an upper annular chamber (15) having an inlet (3) and an outlet (4). A fixed partition panel (13) is provided fitted in the upper annular chamber (15) immediately downstream of said outlet (4) with respect to the direction of movement of the rotor (5). In said peripheral portion (7) of the rotor (5) radial blades (8) are arranged sliding, guided to slide in the direction of the rotor axis (5) in grooves (9) according to a preselected program enabled by a fixed lower cam (14) and by a cooperating fixed upper cam (10) comprising a first narrow portion (11) with descending ramp positioned in proximity of the central cylindrical part (6) of the rotor (5) immediately upstream of said panel (13). The upper cam (10) also comprises an auxiliary cam (16) made up of a second narrow portion with descending ramp positioned immediately upstream of said panel (13) and in proximity of the outer side edge of the peripheral part (7) of the rotor (5) to cooperate with said upper cam (10) for the downward movement of the blades (8) below said panel (13).
