Abstract: An electric motor driven portable air compressor consists of a reciprocating piston and cylinder arrangement with an intake throttling valve operative to unload the compressor above a predetermined pressure level. The throttling valve is a spring loaded plunger responsive to compressor output to close one of two inlet openings to reduce the charge of air in the cylinder. A stainless steel intake leaf spring is disposed between the cylinder and a two part die cast housing and is responsive to cylinder suction for control of the compressor.

Abstract: Disclosed is a rear view mirror assembly of the antiglare, "day or night", type which is readily attachable, such as to the face of an existing rear view mirror in a motor vehicle.The mirror assembly comprises a mirror unit (26) operable between two angularly displaced reflective positions. A cam lever (24) comprising first and second cams (48, 54) cooperates with first and second cam followers (36, 38) to move the mirror unit between the two positions. The mirror assembly preferably includes adhesive strip means (22) to secure the assembly to a support. The cam followers are preferably located on the rear wall (40) of the mirror unit such that vertical movement of the cam lever pivots the mirror unit between the operable positions, one for day driving and one for night driving. This simple, vertical actuating movement minimizes forces tending to displace the mirror assembly from the support.
