Hydraulic actuator
A hydraulic actuator 10 and a material handling machine (90, Figure 1) are provided. The hydraulic actuator 10 includes a body 12 defining a bore 40 having a first end surface (71, Figure 3), a second end surface 72, and a bore surface 39, and a piston 14 slidable in the bore 40. The piston 40, bore surface 39 and first end surface define a first chamber 81; and the piston 40, bore surface 39 and second end surface 72 define a second chamber 82. The body 12 also includes a partition wall feature 34 which in part defines an accumulator chamber 83 and a fluid passage 60 within the partition wall 34 which allows the flow of fluid between the first chamber 81 and the accumulator chamber 83. An accumulator 20 is received in the accumulator chamber 83 and a valve 18 selectively opens and closes the fluid passage 60. A material handling machine 90 incorporating such a hydraulic actuator 10 is also disclosed.
