A flow restrictor (1) for application in bearing formation between a piston (2) and a cylinder (3) of a gas compressor (4). The gas compressor (4) includes a pad (5) externally surrounding the cylinder (3) and an inner cavity (6), arranged between the pad (5) and the cylinder (3), fluidly fed by a discharge flow arising from a compression movement exerted by the piston (2) within the cylinder (3). The gas compressor (4) includes a bearing formation gap (7) separating a piston outer wall (2) and an inner cylinder wall (3), and a flow restrictor (1) is provided with a housing (12) fluidly associating the inner cavity (6) to the bearing formation gap (7). The flow restrictor (1) includes a porous element (8), associated to the housing (12), provided with at least a restrictor part provided with a porosity sized to limit the gas flow flowing from the inner cavity (6) to the bearing formation gap (7). |
