Abstract
In a poppet valve the guide attachment (2) of each sealing member (1) together with the spring (5) is arranged and supported in a cup-like suspension member (8) inserted in a continuous receiving bore (15) in the catcher plate (3) and is guided with its external periphery at least in part directly on the internal periphery of the suspension member (8), as a result of which the guide length of the sealing member (1) and thus the length of stroke thereof becomes independent of the thickness of the catcher plate (3). As a result, the production, assembly and storage are simplified and new fields of application for valves of this type are opened up.
Claims16
An automatic valve for use with a gas compressor comprising:
- a seating member which defines an opening therethrough through which gas can flow,
- a catcher plate positioned adjacent said seating member which defines a receiving bore therein which is aligned with said opening in said seating member,
- a cup-shaped suspension member positioned in said receiving bore of said catcher plate such that said suspension member is open towards said opening in the seating member,
- a sealing member which has an enlarged head and a generally hollow cylindrical base, the cylindrical base of said sealing member being located in said suspension member and the enlarged head thereof being located between said suspension member and said opening in the seating member, said cylindrical base of said sealing member contacting a sidewall and being guided within the suspension member to be movable towards and away from said seating member so that the enlarged head of the sealing member can block or unblock said opening in the seating member, said enlarged head being guided exclusively by said cylindrical base, and
- a spring member located within the cylindrical base of said sealing member and contacting a base of said suspension member to bias the sealing member towards said seating member so that the enlarged head thereof will block said opening in the seating member.
