  • the spool 80 In Fig. 1 the spool 80 is shown in its second position, which is present when there is a pressure at the control port 54. When there is no or a very low pressure at the control port 54 the spool is urged 80 into the first position by the spring 81. In the second position shown in Fig. 1 the spool 80 provides a first fluid connection from the first chamber 41 to the second chamber 42 and a second fluid connection from the third chamber 43 to the fourth chamber 44. There are no further fluid connections between the first to fourth chamber 41; 44 in the second position of the spool 80.
