Abstract: A mechanical pipe joint assembly is provided that connects pipes of different diameters. The mechanical pipe joint assembly includes an annular pipe socket end with an annular cavity located adjacent thereto. A gasket includes first and second sections. The first section includes an arcuate head and an abutment adjacent the arcuate head. The second section includes a lip extension located adjacent the abutment of the first section. The arcuate head of the first portion of the gasket is configured to be circumscribed in the annular cavity of the annular pipe socket. The lip extension of the gasket is configured to be located underneath a tab on a gland portion of the joint assembly and configured to fill space underneath the tab and above the pipe wall.

Abstract: A dual-valve reverse poppet thermostat for use in a vehicle cooling system. The thermostat includes a cup having a temperature sensitive element that actuates a piston causing the piston to move axially upwards. Movement of the piston initiates the gradual opening of a preliminary valve to initiate coolant flow and equalize pressure to open a main valve. The preliminary valve and main valve are biased towards a closed position by biasing spring members.
