The disclosure herein relates to a single acting hydraulic cylinder (100) configured to provide a smooth extension stroke of a piston (102). The cylinder (100) includes a piston rod (108) connected to the piston (102), wherein the piston rod (108) has a plurality of orifices (110) defined at pre-determined positions, and the piston (102) has a groove (106) defined in fluid communication with the orifices (110) and a fluid gallery (104) defined in the piston (102). The orifices allow fluid to flow from an annular side chamber (124) to a full-bore side chamber (125) via the fluid gallery at end of extension stroke, to gradually dampen impact of the piston (102) with a cylinder head end cover (130). The cylinder prevents jolts and jerks in a hydraulic system, provides better control, and ease in operation.
A single acting hydraulic cylinder (100) comprising:
The single acting hydraulic cylinder (100) as claimed in 1, wherein said single acting hydraulic cylinder (100) includes a check valve (128) disposed within said piston (102), wherein said check valve (128) is configured to restrict fluid to flow from said annular side chamber (124) to said full-bore side chamber (125) adjacent to a cylinder cap end cover
(132) in said cylinder head end cover (130) in a sequential manner thereby reducing the speed of movement of said piston (102) towards said cylinder head end cover (130) when said piston (102) is moved from said initial position (P1) to said extended position (P2).
(140) of said cylinder (100) during smooth cushioning at end of extension stroke;
