Abstract
The lip-type seal comprises six members including the external annulus ( ), the first seal member ( ), the reinforcement member ( ), the retention member ( ), the second seal member ( ) and the internal annulus ( ). The first seal member ( ) is made of elastomer and the second seal member ( ) is made of synthetic resin. The reinforcement member ( ) is formed as the insertion member in the first seal member ( ) so that the reinforcement member ( ) extends as far as the end of the hermetic space side of the first seal member ( ) and the first seal member ( ) exists on both sides of the reinforcement member ( ). The reinforcement member ( ) has flexibility to provide an appropriate tension which is generated by the deflection thereof, to the seal part ( ) when the inner pressure P in the hermetic space A becomes high, in a condition that the lip-type seal is attached to a compressor.
