Abstract: The present invention relates to an improved rubber sealed plunger assembly of electrical compressor by-pass valve. The present invention relates to an improved rubber sealed plunger assembly of electrical compressor by-pass valve with lip seal design to eliminate its over molding and improve performances like leakage and response time. The present invention provides an improved rubber sealed plunger assembly comprising of components including but not limited to a rubber disk cover, a rubber disk, a plunger body, a diaphragm and a diaphragm holder.

Abstract: The present invention provides a blow-off valve for an internal combustion engine. More specifically, the invention provides a blow-off valve with dual axis internal seal ring that works in axial and radial direction to improve the leakage while reducing the child parts of assembly. The blow-off valve provided comprises of a plunger body, a compression spring, a moving core, a two axis internal seal ring, a fix core, a bobbin, coil, coil housing, a plunger housing and terminals to power up the coil.
