    Abstract: The invention relates to fluid pressure motors and pumps of the type having a gerotor displacement mechanism and an axial type of valve. The casing has inlet and outlet ports and a speed and load control port. The rotary valve has first and second sets of alternately arranged passages with one set having the usual constant fluid communication with the casing outlet port. The other set of valve passages includes some passages in constant fluid communication with the casing inlet port and at least one passage in constant fluid communication with the casing control port. A change over unit has a fluid supply inlet, a fluid exhaust outlet and a control outlet connected to the casing control port referred to above. The change over unit has means for selectively and alternately connecting the control port to the supply inlet and exhaust outlet thereof.

    Abstract: The invention relates to a gerotor type motor or pump in which the valving is between the gerotor star member and the adjacent casing wall. A separate valve member, as such, is not provided. The valving includes recesses formed in the star, each of which sequentially moves into fluid communication with inlet and outlet recesses formed in the casing wall. The star member has the usual combined rotary and orbital movements and the valve recesses are accordingly formed or shaped to accommodate this compound movement.
