Abstract
A swash plate type automotive air conditioning compressor that minimizes part count while providing a more robust and improved operation. A large diameter, single slotted ball located in a matching socket in each piston overlies the outer edge of the swash plate. As the plate turns, the sides of the plate rub along the sides of the ball slot, and the ball twists within the socket, reciprocating the piston. The larger diameter surfaces of ball and socket are easier to machine accurately, and part count is reduced to a minimum. The larger contacting surface areas provide for better lubrication and lower pressure loading.
