Abstract: A push on fastener 10, 48, 70, 78 comprised of a supporting base 12, 54, 80, a body with threaded nut portions 20, 58, 86 and a split annular web 16, 56, which extends inwardly from one side of the supporting base to the threaded nut portions. The split annular web enables the fastener to be firmly tightened and eliminates the possibility of back slippage.

Abstract: A diverter valve device including a valve body with inlet portions and first and second outlets, a central passage, a flow control orifice, a valve seat and valve member reciprocatable within and partly received within the body and having an internal passage with a first end within the body and a second end forming a second outlet. A first seal is positioned for selectively closing the flow control orifice when the valve member is in the first position, and a second seal for closing the first end when the valve member is in the second position. The valve member is mechanically biased to the first position, and includes surfaces constructed to be acted upon by the pressure of fluid flowing through the body to retain the member in the second position during such flow.
