BRAKING DEVICE AND PIECE OF FURNITURE OR HOUSEHOLD APPLIANCE WITH BRAKING DEVICE Russian patent published in 2021 - IPC E05F5/10 

FIELD: furniture; household appliances.

SUBSTANCE: invention relates to a braking device of a piece of furniture or a household appliance for braking a movable part of a piece of furniture or a household appliance. The braking device of a piece of furniture or a household appliance for braking a movable part of a piece of furniture or a household appliance contains a case filled with a viscous fluid and an element movable in it. Viscous fluid provides the possibility of braking the movement of the movable element in at least one flow section, wherein it is possible to change a geometric shape of the specified at least one flow section, when the ambient temperature changes, wherein the case is cylinder (1), while the movable element in it is piston (2). The specified at least one flow section is at least one flow channel that provides the possibility for fluid to flow through it in cylinder (1) from the first section of the cylinder to the second section of the cylinder separated by piston (2). The specified at least one flow channel has a gap located radially or annularly around piston (2), wherein valve plate (6) is located on the end surface of piston (2), made with the possibility of influencing the flow resistance of the specified at least one flow channel depending on the temperature. Valve plate (6) consists of a combination of materials with a bimetallic effect, and it is made with the possibility of changing its shape depending on the temperature, wherein at least one section of valve plate (6) is made with the possibility of increasing the degree of coating and/or closing an inlet or an outlet of the specified at least one flow channel with increasing temperature. A spacer element is located between the piston and valve plate (6), wherein a diameter of the spacer element is smaller than a diameter of the valve plate.

EFFECT: constant braking characteristics in the widest temperature range.
