Abstract:
1. A low pressure, water or water based fluid powered motor constructed from corrosion resistant material, comprising (i) a non-rotatable cover (k); (ii) a cylinder block (c) housed within said non-rotatable cover (k), wherein the cylinder block (c) is rotatable; (iii) a plurality of bores provided with said cylinder block (c); (iv) a plurality of reciprocating pistons (d), each of the plurality of reciprocating pistons is housed within a respective bore of said plurality of bores of said cylinder block (c) and is provided at one end a crown (d (v) a ball (f), rotatable in each of said spherical seating cups (d (vi) ports (L (vii) a non-rotatable manifold block (n) incorporating a plurality of manifold ports (s), each of said plurality of manifold ports is radially disposed at equal intervals in a non-rotatable manifold block end face and adjacent said plurality of reciprocating pistons (d), said plurality of manifold ports (s) are linked to galleries connected to a higher pressure fluid delivery circuit and a lower pressure fluid return circuit, wherein grooves (m (viii) an output/input shaft (a) connected to said cylinder block (c); (ix) a rotary commutation multi-ported face plate (i) interposed between said cylinder block (c) and said non-rotatable manifold block (n), mounted on said output/input shaft (a), and adapted to engage one of said non-rotatable manifold block end face and a cylinder block end face under spring bias; (x) an undulating lobe cam track (e), having two to six lobes, is attached to said non-rotatable cover (k) and defines multiple crests and troughs; and (xi) each ball (f) is adapted to engage with said undulating lobe cam track (e), characterized in that
