Definitions

  • the present invention relates to a device for adjusting the advance of the phase-timing of hydraulic engines.
  • the supply fluid requires a certain amount of time to pass through the ducts which lead from the rotating distributor to each propulsor (supply stage) and vice versa (discharge stage), resulting in the need to determine beforehand the correct phase-timing of the engine, or the instant at which opening/closing of the duct supplying/discharging the fluid to some of the propulsors occurs, so that it is synchronized with the corresponding discharging/supplying of the other propulsors.
  • This adjustment of the advance is, however, necessarily associated with the speed of rotation of the engine since, with an increase in the speed of the engine and hence the speed with which each propulsor changes phase (supplying/discharge), the delay in supplying/discharging of the fluid causes malfunctioning of the engine.
  • the technical problem which is posed, therefore, is that of providing a device which allows control and adjustment of opening/closing of the ducts supplying/discharging each propulsor of an hydraulic/oleodynamic propulsor upon variation in the number of revolutions of the engine itself.
  • said device should be simple and low-cost to manufacture and should be able to be operated both manually and automatically by associated control means.
  • a device for adjusting the advance of hydraulic engines provided with propulsors actuating an eccentric drive shaft and a rotating group for distribution of the fluid actuating the propulsors, said rotating distribution group comprising at least one plate mounted idle on the drive shaft and means designed to co-operate with said plate so as to cause rotational operation thereof relative to the drive shaft, said rotation being able to be actuated in both directions and between predetermined angular end-of-travel positions.
  • an engine 10 of the oleodynamic type is composed essentially of a casing 11 which is closed by covers 12 and houses, internally, radial cylinders 13, each of which is placed in communication with a rotating distributor 20 (Fig. 2) which designed to open/close the ducts for supplying/discharging the cylinders so that the latter are cyclically compressed/discharged and are able to exert their thrusting action on an eccentric shaft 14 which is supported on the casing 11 of the engine by means of associated bearings 11b.
  • Said rotating distribution group (Fig. 3) consists of an external container 21 which is fixed to the casing 11 by means of bolts 21a and which has inside it, arranged coaxially, a plate 22 mounted idle on an extension 14a of the shaft 14 on which it may rotate in both directions.
  • the plate 22 is provided with openings 22a for connection to the ducts 13a supplying/discharging the cylinders 13.
  • a rotating distribution disk 23 bears against the plate 22, coaxially therewith, and is in turn provided with through-ducts 23a and pushed against the plate 22 by a reaction ring 24 provided with a prestressed spring (not shown) arranged between the ring 24 and the cover 21 of the distributor.
  • the plate 22 has a radial extension 22b which is designed to engage with the device 30 for adjusting the advance in accordance with the invention which causes rotational actuation thereof.
  • said actuating device 30 (Fig. 4) consists of a pair of cylinders 31 formed in the casing 11 of the engine in an opposite position with respect to that of the radial extension 22b of the plate 22.
  • Said cylinders 31 are closed towards the outside by an end-piece 31a and have, arranged inside them, corresponding coaxial pistons 32 provided with associated seals 32 which act on the opposite radial surfaces of the extension 22b of the plate 22.
  • the appropriate supplying/discharging of the two cylinders 31 causes the corresponding advance/retraction of the two pistons 32 towards/away from the radial extension of 22b the plate 22 with the consequent thrust on either side thereof and rotation in the clockwise/anticlockwise direction of the plate itself.
  • Said rotation of the plate 22 causes the desired effect of an advance in the opening/closing of the supply/discharge ducts of the cylinders 13 since it causes the angular displacement of the circumferential position of the holes 22a where the openings of the plate are aligned with the openings 23a of the rotating disk 23, allowing flowing of the fluid.
  • Figs. 6a and 6b illustrate respective variations in examples of embodiment of the device according to the invention and comprising: two cylinders 131 with a single piston 132 provided with a seat 132a designed to engage with the extension 22b of the plate 22 (Fig. 6a); or a single double-delivery cylinder 231 with piston 132 having a seat 132a for engagement with the extension 22b (Fig. 6b).
  • control means 40 which are designed to supply correspondingly the fluid to the cylinders 31 are envisaged.
  • said automatic control means 40 comprise a sensor 41 which is designed to detect the speed of rotation of a disk 41a associated with the drive shaft 14 and send a corresponding signal to a control board 42 which emits pulses operating a distributor 43 which, in turn, drives a metering valve 44, the outputs of which control supplying/discharging of the two cylinders 31 and the consequent advance/retraction of the pistons 31.
  • the operating group 40 causes total supplying/discharging of the two cylinders and the consequent displacement of the pistons 32 as far as the respective end-of-travel stop, on either side; this means that the plate 32 rotates between two fixed angular positions and stops only in said positions, causing a predefined advance suitable for a predetermined and precise value of the speed of rotation of the drive shaft.
  • Said means comprise all the operating means 40 already described above and a blocking valve 145 arranged between the metering valve 44 and the cylinders 31; the blocking valve is designed to ensure balanced supplying of the two cylinders 31, blocking the pistons 32 in any intermediate position between the two end-of-travel positions.
  • means 150 for manual operation of the device for rotational actuation of the plate are also provided.
  • the radial extension 22b of the plate 22 engages in a seat 152a of a rod 152, one end of which is connected to a screw 151, the other end of which projects outside the casing 11 of the engine and is integral with a manual operating knob 151a.
  • the opposite end of the rod 152 has a fork 152b inside which a safety end-of-travel pin 153 preventing rotation of the rod 152 about its longitudinal axis is inserted.
  • the manual operating system could also be realized by means of the metering valve 44 supplied by means of a circuit, the opening/closing of which is controlled manually by the operator.
  • the adjusting device is of the tangential type, although actuating systems of the radial and axial type are also envisaged, as described below with reference to the respective figures.
  • the device of the radial type envisages that the two cylinders 331 are arranged in substantially radial directions; in this case the respective pistons 332 have a surface 332a which is inclined towards the end and towards the inside of the piston and is designed to co-operate with a corresponding inclined surface 122c of the radial extension 122b of the plate 22.
  • the alternate thrusting operation of the two pistons 331 causes the thrusting of the associated inclined surface 332a onto the corresponding inclined surface 122c of the radial extension 122b with consequent rotation, in one direction (Fig. 9a) or in the other direction (Fig. 9b), of the disk 22.
  • the inclination of the inclined surfaces is such as to make the movement of the plate irreversible.
  • the adjustment of the advance can be controlled by means of a sensor 141, for example of the inductive type, which is designed to detect passing of a mass consisting, for example, of the head of a screw 141a screwed onto the disk 22 in a suitable position or of a block 141b located in the same position.
  • a sensor 141 for example of the inductive type, which is designed to detect passing of a mass consisting, for example, of the head of a screw 141a screwed onto the disk 22 in a suitable position or of a block 141b located in the same position.
  • the radial device is of the irreversible type since, when there is no pressure in the cylinders, the shape of the inclined surfaces does not allow free rotation of the plate 22.
  • manual operating means may be envisaged, said means consisting of a pair of threaded rods similar to that illustrated in Fig. 8, but arranged in a substantially radial direction in place of the pistons 432: in this case the end opposite to that of the knob 151a will have an inclined surface for cooperating with the corresponding surface 122c of the radial projection 122 of the plate 22.
  • Figs. 10a, 10b finally show the axial embodiment of the device for performing adjustment of the advance according to the invention.
  • rotation of the disk 22 is performed by rotation of a cam 423 actuated by the shaft 431a of a conventionally controlled actuator 431.
  • the cam of the adjusting device is housed inside a radial seat 222c of the disk 22.
  • the presence of the controlled actuator provides the device for performing adjustment of the advance with an intrinsic reversibility.
  • said means for performing rotation of the plate 22 may be directly connected to the engine supply so as to provide automatic adjustment in both directions of rotation of the phase advance of the distribution.
  • the device according to the invention allows simple and effective manual or automatic adjustment of the advance with which the rotating group for distribution of the fluid open/closes the supply/discharge ducts of the cylinders of the engine, allowing perfect phase-timing thereof even when there is a variation in the speed of rotation of the engine.
