Abstract

856,693. Pistons. NORTH AMERICAN AVIATION Inc. Aug. 11, 1958, No. 25717/58. Class 122 (1). [Also in Groups XXVIII and XXIX] In a radial cylinder pump or motor the pistons each comprise a piston and slipper assembly 10. The piston portion is thinwalled and of steel and has a spherical portion 40 engaging the cylinder bore; secured within the piston is an aluminium plug 44 which forms with the piston a passage 46 so that liquid from the cylinder may flow through a non-return valve 49 to a lubrication basin 47 within the slipper portion 12 which has a spherical portion 13 engageable with the track ring 5. Differential expansion between the plug 44 and the piston reduces the passage 46 when the temperature of the pump and liquid increases. A groove 52 is also formed between the piston and plug 44 so that liquid pressure expands the piston into contact with the cylinder. The piston surface may also flatten under load to increase the area of contact with the cylinder bore.
