Abstract
A thermal relief device (1) is described comprising a housing (2) having an inlet (3) and an outlet (4) connected by a relief channel (5). Such a thermal relief device should have a simple construction. To this end a microporous structure (10) is arranged between inlet (3) and outlet (4).
Claims19
A hydraulic thermal relief device for protecting a hydraulic system comprising a housing having an inlet and an outlet connected by a relief channel, wherein a microporous structure is arranged between inlet and outlet, wherein the microporous structure is in form of a frit, wherein a flow rate of hydraulic fluid through the hydraulic thermal relief device is controlled by a pore size and a thickness of the microporous structure, and wherein the pore size and the thickness of the microporous structure are configured to protect the hydraulic system when the hydraulic system is pressurized beyond a predetermined threshold value.
A hydraulic thermal relief device comprising a housing having an inlet and an outlet connected by a relief channel, wherein a microporous structure is arranged between inlet and outlet, wherein the microporous structure is part of the housing, wherein the housing including the microporous structure is a 3D printed structure, wherein a flow rate of hydraulic fluid through the hydraulic thermal relief device is controlled by a pore size and a thickness of the microporous structure, and wherein the pore size and the thickness of the microporous structure are configured to protect the hydraulic system when the hydraulic system is pressurized beyond a predetermined threshold value.
A hydraulic thermal relief device comprising a housing having an inlet and an outlet connected by a relief channel, wherein a microporous structure is arranged between inlet and outlet, wherein the microporous structure is part of the housing, wherein the housing including the microporous structure is produced by a method of sintering with regions of differing densities, wherein a flow rate of hydraulic fluid through the hydraulic thermal relief device is controlled by a pore size and a thickness of the microporous structure, and wherein the pore size and the thickness of the microporous structure are configured to protect the hydraulic system when the hydraulic system is pressurized beyond a predetermined threshold value.
