Single acting hydraulic cylinder with head end cushioning

A single acting hydraulic cylinder (100) comprising:

• a piston (102) adapted to be actuated hydraulically for moving said piston (102) from an initial position (P1) to an extended position (P2);
• and
• a piston rod (108) connected with said piston (102), wherein said piston rod (108) has a plurality of orifices (110) defined at pre-determined positions therein,
• wherein
• said piston (102) has a groove (106) provided in fluid communication with said plurality of orifices (110) of said piston rod (108) and a fluid gallery (104) defined in said piston (102);
• and
• said plurality of orifices (110) are adapted to allow fluid accumulated in an annular side chamber (124) of a cylinder housing (122) to flow into said fluid gallery (104) through said groove (106), and the fluid from the fluid gallery (104) flows to a full-bore side chamber (125) of said cylinder housing (122), and each of said orifice (110) is sequentially covered by a cushioning seal (132) provided in a cylinder head end cover (130) of said hydraulic cylinder (100) to block flow of fluid from said annular side chamber (124) to said orifices (110) for reducing a speed of movement of said piston (102) towards said cylinder head end cover (130) thereby dampening impact of said piston (102) with said cylinder head end cover (130) at end of an extension stroke in which said piston (102) is moved to said extended position (P2).
