摘要： A braking system for farm tractors and similar vehicles, comprising a differential braking system and a hydraulic system for the braking assistance forming a system unit (H) which includes two circuit branches (H1,H2), each circuit branch operating the braking with respect of one side of the vehicle. According to the invention, to said system unit (H) are applied, through connection interfaces (36,37), two control units (C1,C2), each control unit including an electrovalve (20) and a distributor (24) operated by said electrovalve, each said distributor (24) controlling the operation of the system unit (H) with respect to one of the circuit branches (H1,H2), and each said electrovalve (20) being singularly controlled by an electronic control circuit (EL) provided with sensors (V,R,P,A) of the main vehicle parameters, such as a sensor (V) of the vehicle speed, sensors (R) of the speed of singular wheels, sensors (P) of the positions of the braking pedals and a sensor (A) of the position of the accelerator pedal. In this manner the vehicle is equipped with a function of regulation of the slip in traction (ASR), or with a function preventing the wheel blockage in braking (ABS), or with a function of stability control (ESP), or with several of these and other functions, having a great utility to the aim of security when the vehicle runs on road at a high speed.

摘要： A vane for a displacement pump comprising a body (1), a profiled pumping chamber (2) defined within said body (1), and a rotor (4) rotatably mounted within said body (1), eccentric with respect to the pumping chamber (2) and carrying a vane (5) whose end portions slide against the inner surface (3) of the pumping chamber (2), characterized in that each operating end portion of the vane (5) is formed by a tilting tip (9) having a coupling means (11) articulated with respect to the vane body (5) and suitable for tilting within a limited field with respect to the vane body (5), the shape of the tip (9) and the allowed tilting field being such that the tilting tip (9) is applied against the inner surface (3) of the pumping chamber (2) when the vane (5) is rotated in a preestablished working direction (F1), and being such that the tip (9) is allowed to retract from the inner surface (3) of the pumping chamber (2) when the vane (5) is rotated in the direction (F2) opposite to the preestablished operating direction (F1). The invention also concerns a rotary displacement pump comprising at least a vane with tilting tips.

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.
