摘要： A rotor (1 -3) moulded of plastic material, intended for rotary installation in a cavity of a pump body and for reception of one or more vanes forming the pumping members, characterized in that at least a part of the surfaces thereof, intended to undergo sliding displacements against other pump members, is covered by at least one metallic foil (4) caused to adhere to the subjacent surface of plastic material. The metallic foil can consist of a steel sheet or an aluminum alloy sheet, intended for reducing the resistances to the sliding as well as for mechanically reinforcing the rotor. The metallic foil can be fastened to the plastic material body (1 ) of the rotor by a co-moulding operation, or it can be meehanically fixed to the body (1 ) of the rotor moulded of plastic material. The metallic foil may be shaped in order to cover only an end portion of the rotor, or even to also line the space formed within the rotor for receiving one or more vanes.

摘要： A displacement pump driven by a motor, wherein a barrier (4.1; 8; 2.2) suitable for preventing or reducing the fluid leakage is inserted in at least one of the pump regions which are subjected to a leakage between the inner space of the pump and the outside. In one embodiment, in one of two component parts (2,4) subjected to relative movement is formed at least one step (4.1 ) which determines a limited region of mutual contact between the two component parts (2,4) subjected to relative movement, thus forming a sort of labyrinth which favores the seal against the fluid leakage. As an alternative, on one of the two component parts (2,4) subjected to relative movement is provided an annular inclined area (4.2) located facing a seat (2.1 ) for an annular sealing element (8) whereby, due to the pressure difference between the inner fluid and the outer fluid, the annular sealing element (8) is biased to contact against the annular inclined area (4.2). Moreover, the sealing barrier (2.2) can be provided in the region wherein there is a coupling joint (5) driving the rotor (4), by forming on the support member (2) a step (2.2) which acts as a closure for the rotor (4) and keeps in position the driving coupling joint (5), the coupling clearance being annulled by the oil penetrating between the parts.

摘要： A pump (1) of the vane type wherein the vane (5) has a high flexional elasticity and, preferably, is mounted in the pumping chamber (2) under stress, in the absence of any clearance or with interference. The flexional elasticity of the vane (5) is so chosen that it always provides a suitable sealing contact with the wall (3) of the pumping chamber (2), that it sustains without deformations the stresses which are normal during the pump operation, and that it elastically yields without damage in the presence of abnormal stresses, whereby the vane (5) operates as a limiter of the maximum torque that can be transmitted, and it inflects when a pre-established maximum stress is overcome. The vane (5) may be provided with end point members (6) applied to the vane (5), or even the end portions of the vane (5) may be suitably shaped in order to correctly glide against the wall of the pumping chamber. The vane (5) can be manufactured of a material of the group comprising metals, plastics, rubbers, carbon based materials and other synthetic materials.
