Abstract: Apparatus for distributing condensate over an outdoor heat exchanger of an air conditioner unit wherein the outdoor heat exchanger and an outdoor fan are enclosed within a housing. An orifice is located in the bottom of the housing adjacent to the fan and condensate produced in the unit is brought to the entrance of the orifice. The orifice is connected to a reservoir that directs condensate passing through the orifice to a point beneath the outdoor fan where the condensate can be picked by the fan and distributed over the heat exchanger surfaces. The size and shape of the orifice is matched to the pressure differential produced over the fan so that condensate is drawn rapidly into the housing and distributed by the fan over the outdoor heat exchanger.

Abstract: Reciprocation of the vane of a rolling piston compressor can produce a pumping action which draws oil from the sump and discharges it into the gas exiting from the discharge chamber. By providing a restricted communication between the sump and the spring cavity, the amount of oil being pumped can be reduced to a level just sufficient for lubricating the vane.
