Abstract: The scroll compression device includes a first scroll element (11) having a first base plate (13) and a first spiral wrap (14); a second scroll element (12) having a second base plate (15) and a second spiral wrap (16), one of the first and second scroll elements (11, 12) being configured to perform an orbiting movement in relation to the other one of the first and second scroll elements, the first and second scroll elements (11, 12) intermeshing with each other and delimiting compression chambers (17); and a sealing device (28) arranged in an end face (19) of the first spiral wrap (14) and having a sealing surface configured to cooperate with the second base plate (15). The sealing device (28) is configured to allow fluid flow from an upstream compression chamber to a downstream compression chamber through the sealing surface when the pressure in the upstream compression chamber exceeds the pressure in the downstream compression chamber, and the sealing device (28) is configured to prevent fluid flow from a downstream compression chamber to an upstream compression chamber through the sealing surface when the pressure in the downstream compression chamber exceeds the pressure in the upstream compression chamber.

Abstract: The scroll refrigeration compressor according to the invention includes a sealed enclosure at least partially defining a discharge chamber designed to be connected to a discharge line, and a discharge valve attached on the sealed enclosure and fluidly connected to the discharge chamber. The discharge valve includes a valve body, a valve seat, and a discharge check valve movable between a covering position and a released position. The discharge valve includes deflection means positioned in the valve body and arranged to orient the flow of refrigerant coming from the discharge line at least partially toward the periphery of the discharge check valve.

Abstract: The scroll compressor comprises a fixed scroll having a fixed end plate and a fixed spiral wrap extending from the fixed end plate; an orbiting scroll (9) having an orbiting end plate and an orbiting spiral wrap extending from the orbiting end plate, the fixed spiral wrap and the orbiting spiral wrap meshing with each other to form compression chambers; a vertical drive shaft (19) having a crankpin (21) at an upper end portion of the vertical drive shaft (19), the crankpin (21) including an outer circumferential surface (23) cooperating with an orbiting scroll bearing (24). The crankpin (21) includes a recess (25) formed in an axial end face (26) of the crankpin (21), the recess (25) and an upper portion (27) of the outer circumferential surface (23) defining therebetween a circumferential wall (28) extending along at least a part of the circumference of the crankpin (21), the circumferential wall (28) being deformable in a radial direction during operation of the scroll compressor.
