Definitions

  • valve projection (41b) is connected to the discharge port as in the related art. According to the shape of (29) It is not necessary to form them. Thereby, the cost of processing and assembling the discharge port (29) and the reed valve (41) can be reduced. Further, the above-described sealing mechanism can ensure the sealing performance comparable to that of the conventional simple flat reed valve.
  • FIG. 4 is a cross-sectional view showing an open state of a reed valve according to Embodiment 1 without a valve press.
  • FIG. 7 is an enlarged cross-sectional view showing a discharge valve mechanism according to Embodiment 4 without a valve press.
  • the discharge port (29) includes an inlet (29a) opening to the compression chamber (25b) and an outlet (29b) opening to a space in the casing (10).
  • the inner surface (2a) of the discharge port (29) is formed in a tapered shape extending from the inlet (29a) to the outlet (29b).
  • the discharge port (29) is formed in a tapered shape, so that the inner surface (2a) of the discharge port (29) and the valve
  • the cross-sectional area S of the flow path formed between the protrusion (41b) and the side surface (4a) is larger than, for example, when the discharge port is formed in a cylindrical shape.
  • the seat surface (2b) and the valve flat portion (41a) are formed flat. Therefore, the cost required for processing and assembling is reduced as compared with the related art, and the sealing performance is not inferior to that of the conventional simple plate-shaped lead valve.
  • the seat surface (2b) is formed in a convex shape, the contact area between the valve plate portion (41a) and the seat portion (22b) is smaller than before, and the valve plate portion (41a) and the seat portion are smaller. Since the contact pressure acting between (22b) and (22b) increases, sealability is reliably ensured.
  • the high-pressure refrigerant does not flow backward from the inside of the casing (10) to the compression chamber (25b). . Thereby, a decrease in volumetric efficiency can be suppressed.
  • valve projection (41b) is formed in a conventional manner. It is not necessary to form the shape according to the shape of the discharge port (29). Thereby, the cost of processing and assembling the discharge port (29) and the reed valve (41) can be reduced.
  • the flow passage area S formed between the inner surface (2a) of (29) becomes larger. Therefore, the above lead Insufficient flow area at the beginning of opening of the valve (41) can be suppressed. As a result, overcompression loss can be further reduced.
  • Other structures, operations and effects are the same as those of the first embodiment.
  • the force described for the so-called rotary piston type compressor (1) may be applied to a so-called swinging piston type or scroll type compressor.
  • a compressor provided with a so-called poppet-type lead valve (41) at the discharge port (29) of the compression chamber (25b), which is the working chamber.

Abstract

Une soupape flexible (41) d'une ouverture de décharge (29) présente une section en plaque plane (41a) et une section en saillie (41b), formée côté tête de la section en plaque plane (41a) de la soupape, laquelle soupape entre dans l'ouverture de décharge (29) et sort de cette dernière. L'ouverture de décharge (29) présente des parois coniques s'étendant d'une entrée (29a) vers une sortie (29b) et la section en saillie (41b) de la soupape présente une forme plus étroite, de sorte qu'un espace est formé entre cette section en saillie et une surface intérieure (2a) de l'ouverture de décharge (29). De plus, une section de siège (22b), avec laquelle la section en plaque plane (41a) est en contact, est formée au niveau d'un bord extérieur de la sortie (29b) de l'ouverture de décharge (29).
