Abstract
530,595. Swash-plate pumps. MERCIER, J. June 28, 1939, No. 18795. Convention date, July 6, 1938. Addition to 468,122. [Class 102 (i)] A pump constructed according to the parent Specification, comprising a number of parallel pistons 1 actuated by a rotary swash-plate 2 of varying angularity, has the pivot 3 by which the swash-plate is secured to the driving shaft 4 located within the circle formed by the points of contact of the pistons with the swash-plate. The swash-plate is given its angular position by means of a spring 6 and a central plunger 5, this angularity being reduced by the reaction of the pistons when the load on the pump exceeds a pre-determined value. Passages 7 in the plunger 5 connect the interior of the hollow driving shaft 4 with the body 8 of the pump and act as a dash pot to reduce vibrations when a small number of cylinders is used.
