摘要： A coil of an electromagnet (29) subjects to an attraction force a moving platine (30) of magnetic material inside which is housed a ball (32) of non-magnetic material closing the end of a passage (33) for the hydraulic fluid. The device further comprises electronic means to supply the coil (29) with a pulse unidirectionnal current of which the cyclic ratio and the mean value are servo-controlled to an order value represented by an electric control signal. The device may be used as a hydraulic potentiometer for defining a pilot pressure proportional to an electric control signal in a hydraulic control circuit of an automatic transmission in industrial vehicles.

摘要： The unit serves to convert an electrical control signal (I) received at the input of the unit into a pneumatic signal (P). This is emitted at the output of the unit and its value should be proportional to the value of the control signal (I). The unit comprises a tongue-shaped piezoelectric element (6) which is loaded with a voltage dependent on the control signal, so that the element (6) carries out a lateral bending movement which varies with the voltage. The unit also comprises a pneumatic line (1) with a chamber (1a) which is supplied with compressed air via a throttle (4) and from which the compressed air is conducted through a nozzle (3) located near to one side of the piezoelectric element (6) so that the air pressure in the chamber is regulated by the piezoelectric element (6) as a function of the said voltage; and an outlet line (5) leading from the chamber for transmitting the regulated air pressure to the control system as the said pneumatic signal (P). To make the pneumatic signal (P) to the control system accurately follow the electrical control signal (1), a pressure transducer (7) is connected to the outlet line (5), being designed to produce an electrical signal (T) which corresponds to the regulated air pressure, and which is fed back via a feed-back circuit to the input of the unit. Furthermore, the input has a circuit (9, 11) which receives both the electrical control signal (1) and the fed-back electrical signal (T). The circuit has a device (9) for forming a difference signal by comparing the two signals (I, T) and a device (11) for integrating the difference signal and thereafter producing from the integrated difference signal the voltage with which the piezoelectric element (6) is loaded.

摘要： An electro-pneumatic transducer has a plate (30, 36) mounted on an electrical coil (2) moveable through a restricted arc in a cylindrical gap in a magnet assembly (14) in response to an electrical analogue signal against a hair spring (22) bias. A nozzle (32, 38) is directed substantially perpendicularly against the plate (30, 36) such that upon rotation of the coil (2) and the plate the distance between the nozzle outlet (34, 40) and the plate is varied to produce a variation in back pressure in the air flow upstream of the nozzle outlet in direct proportion to the electrical analogue signal strength.

摘要： A gauging system (16) includes a source (32) of pressurized fluid, one or more fluid outlet means, each including a novel adjustable valve (20) and fluid line connecting the source of pressurized fluid with a fluid orifice (34) that is located between the elements of a machine or die (21), and one or more pressure transducers (36) connected to measure the pressure in each fluid line. The novel adjustable valve (20) includes threaded members (78, 80) forming a variable flow path providing precisely variable and controllable fluid flow and little restriction at high flow rates. A computer (44) measures the transducer output to determine the distance between mold elements (22, 24). The system is calibrated by measuring each transducer output for a set of distances including the open mold distance, with an esentially infinite hose length. When the system is set up at the customer's location, with a shorter length of hose, the system is brought back into calibration by opening the mold and adjusting each adjustable valve until the transducer output is within specification for the mold open calibration point.

摘要： Improvement to pneumatic sensors for the control of pneumatic cycles wherein a fluid jet pump is supplied at the inlet by a compressed air circuit and is connected at the outlet to a nozzle the stopping of which causes a pressure rise in the fluid jet pump, said rise being used as a control signal of a pneumatic component. The space (4) comprised between the jets (2, 3) of the fluid jet pump is connected on one hand to an outlet orifice (14) emitting the control signal and on the other hand to an air vent valve (13b) which, open during the ejection escape, lets the atmospheric pressure into the space (4), the outlet (14) and the conduit (15) preventing the formation of a depression, and which is closed during the obturation of the escape. The invention is used for the control of pneumatic cycles.
