Abstract
1327487 Hydraulic actuators C H BENNETT 27 Nov 1970 [19 Jan 1970] 56429/70 Headings F1D and F1F [Also in Division B7] An hydraulic actuator 20 comprises a piston 24 reciprocal in a cylinder 21 having heads 22, 23, the head 23 being attached to a support 12 through a strap member 33 integral with the head 23 and a support element 35, the strap member being made of a flexible, preferably plastics, material so that the orientation between the head 23 and element 35 may be varied. The actuator is single-acting and the piston rod 27 is hinged to a bracket 29 on a trim member 11 of a power boat (see Division B7). Fluid flow takes place through passages 39, 34 in the head 23, strap member 32 and support element 35, the fluid pressure acting on a diaphragm which in turn acts on the piston 24 against the force of spring 26. The fluid is supplied by a gerotor pump 40 which draws fluid from a reservoir 41, the outlet of the pump being connected by an orifice to a pressure relief valve 51 leading back to reservoir 41. Thus if excessive pressure occurs in the cylinder of actuator 20 and hence in the pump outlet, valve 51 opens to vent fluid to reservoir 41. An alternative relief valve construction is also described, Fig.8 (not shown).
