Beschreibung
Zusammenfassung:	A piston ring for sealing a cylinder wall to a piston body is provided. The piston ring includes a ring body of an elastically deformable material which extends substantially circumferentially around an axis and has an inner face that faces the axis. The inner face includes a plurality of axially spaced and radially inwardly extending contact features. The ring body configured to bias the contact features into engagement with the piston body to establish a seal therebetween. At least one of the contact features extends substantially continuously around a circumference for establishing a substantially continuous seal around the piston body, and at least one of the contact features is non-continuous and has at least one recessed area for allowing the passage of oil and gas therethrough.
