<p>A suction and discharge valve arrangement for a small hermetic compressor of the type presenting a compression cylinder ( 1 ), which has an end closed by a valve plate ( 10 ) and which has a suction pipe ( 5 ) adjacent to the valve plate ( 10 ) and substantially orthogonal to the cylinder axis, the valve plate ( 10 ) being provided with a discharge orifice ( 11 ) substantially centralized in relation to the axial projection ( 20 ) of the internal contour of the compression cylinder ( 1 ), and with at least one suction orifice ( 12 ), which is internal to said axial projection ( 20 ) of the internal contour of the compression cylinder ( 1 ), and defining at least part of the extension of a suction passage (P), with an end opened to the inside of the compression cylinder ( 1 ) and an opposite end opened and connected to the suction pipe ( 5 ) by means of a transition portion (T), which is configured to minimize load losses.</p> |
