Abstract

Inventia se refera la un dispozitiv electohidraulic de comanda, destinat actionarii motoarelor hidraulice oscilante. Dispozitivul este alcatuit dintr-un bloc electronic, care transmite un semnal de comanda unui motor electric, a carui deplasare unghiulara este transformata de un convertor într-o deplasare liniara. Convertorul este alcatuit dintr-un disc solidar cu axul motorului electric, pe disc fiind fixate niste came care imprima deplasari liniare unor elemente de comanda ale unui bloc de drosele hidrologistice care includ niste rezistente hidraulice de comanda. Rezistentele hidraulice de comanda, împreuna cu niste rezistente hidraulice de alimentare si de evacuare, determina valorile unor rezistente hidraulice de putere, legate în circuitul de alimentare al motorului hidraulic oscilant.The invention relates to an electro-hydraulic control device, intended for the operation of oscillating hydraulic motors. The device consists of an electronic block that transmits a command signal to an electric motor whose angular displacement is transformed by a converter into a linear displacement. The converter is made of a solid disc with the electric motor shaft, and on the disk are fixed some cams that print linear displacements to control elements of a block of hydrological droplets including hydraulic control resistors. Hydraulic control resistors, along with some hydraulic supply and discharge resistors, determine the values of hydraulic power resistors connected in the feed circuit of the hydraulic oscillating motor.
