Abstract: A control valve is provided which may be incorporated within a fluid operating system. The valve has an internally-mounted check element which allows the valve to provide a fail-safe mode for a downstream device in fluid communication with the control valve. The invention includes the control valve, the valve in combination with a downstream device, and a method whereby the flow of pressurized fluid is controlled by operation of the control valve.

Abstract: A retention arrangement for retaining a motor cover and a thermal protection device over one end of a dynamoelectric motor uses connection bolts already available on the motor for mounting the stator and positions the protector in an annulus between the cover side wall and stator end turns and below the upward extension of the stator end turns. The retention arrangement includes a pair of plates being bolted to the motor and encircling the end turns of the stator with first interengageable portions securing the cover to the plates and second interengageable portions securing at least one plate to a holder to which the protector is mounted, such retention assuring that after the air space between the stator and rotor is set a suction duct will be positioned to cool the protection device and the end turns.
