摘要： The invention relates to a hermetic refrigeration compressor of the type including a motor compressor unit (1) suspended within a hermetic case (3). The motor compressor unit (1) comprises a cylinder provided with cylinder head (12) defining suction and discharge chambers with their corresponding values, and a suction muffler set (100). According to the invention, the suction muffles set comprises a small muffler shell (110) mounted outside the cylinder head, and an insulating hollow body (120) lining the suction chamber (13) of the cylinder head (12). A strainer device (118) is fixed between the two half parts forming the hollow body (120). This configuration facilitates the assembling of the strainer (118) and guarantees its tight fixation without any kind of fixing frame or ring. This makes it possible to enlarge considerably the area of the strainer, thus avoiding heat transfer from the metal strainer to the suction gas flow when passing throughout the meshes.

A valve plate is mounted on the cylinder and has a discharge orifice the outer face of the valve plate having a recess with a side wall surrounding said discharge orifice and defining a valve seat. A sealing member is axially movable between a closing position against the valve seat. A backstop member is externally attached to the valve plate so as to limit the axial displacement of the opening sealing member. Guide elements for axial displacement of the sealing member are provided around the latter and mounted between the valve plate and the backstop member. There is a resilient deformable means with an end attached to the backstop member and another end opposite to the first one, provided at a plane adjacent to the outer face of the sealing member, opposite to that face sealing against the valve seat. When the latter is at a closing position of the valve seat, such resiliently deformable means being pressed by the sealing member, from a non-pressed condition to a resiliently pressed condition when the sealing member is displaced from the closing to the opening position, by means of a predetermined pressure value in the cylinder and the resiliently deformable means being guided by the backstop member while it is deformably moved by the axial displacement of the sealing member.
