When the two chambers of a single-piston rod hydraulic cylinder are connected with pressure oil at the same time, the connection method is called a differential connection hydraulic cylinder. In the case of neglecting the pressure loss of the connecting oil circuit of the two chambers, the oil pressure of the two chambers is equal. Because the force area of the rodless cavity is larger than that of the rod cavity, the rightward force of the piston is greater than the leftward force. The oil in the rodless cavity is squeezed out and flows into the rodless cavity, which accelerates the rightward movement of the piston.
