<p>The arrangement can be applied to a compressor which comprises a compression cylinder (11) closed by a valve plate (40) provided with seat regions (43, 44) and with respective suction orifice (41) and discharge orifice (42) which are closed by a sealing end portion (53, 63) of a respective valve vane (50, 60), to be peripherally seated against its seat region (43, 44). The valve plate (40) carries a support means (70), defined in the central region of the contour of at least one of the suction orifice (41) and discharge orifice (42) and incorporated to the valve plate (40) by at least one radial arm (80). The support means (70) has a stop surface (71), against which is seated a central region of the sealing end portion (53, 63) of the respective vane (50, 60), said stop surface (71) defining a projection in relation to the radial arm (80).</p> |
