As shown a spring 46 biases the shaft 17-to a position in which the spline connection 44 is engaged and a manually rotatable cam 49 moves the shaft 17 left against the bias of the spring 46 to disengage the spline connection 44. The cam 49 is fast with a shaft 52 which projects through the reduction gear housing 13 and terminates in a hexagonal head which is rotated by a wrench to operate the cam. In Fig. 5 (not shown) the shaft 17 is rotatable relative to but axially movable with a bolt (56) engaging a threaded bore in the gear housing 13. Rotation of the bolt (56) causes axial movement of the shaft 17 to disengage the spline connection 44. Reduction gearing.-The input pinion 18 meshes a pinion 21 fast with the stun gear 24 of a sun-ring planet train 24, 26, 29 having a fixed ring gear 29 and an output planet carrier 28 fast with a track drive sprocket 11. The sun 24 and ring gear 29 are permitted to float radially. Parking brake.-A spring applied-hydraulically released parking brake 63 comprises discs 66, 67 respectively fast with the pinion 18 and gear housing 13. The brake is engaged by springs 71 acting between a brake housing 70 fast with the housing 13 and a presser plate 68. The brake is released by pressure liquid supplied to chambers 73 and acting through a diaphragm 74, pistons 75, a plate 72 and draw rods 69 to withdraw the pressure plate 68. Pressure liquid is supplied to the brake to release the latter when the hydrostatic transmission is operative to drive the vehicle. To permit towing of the vehicle when the hydrostatic transmission is inoperative and the coupling 44 is disengaged, the brake is released by pressure liquid supplied to the chambers 73 by a hand pump. In Fig. 5 (not shown) the brake acts on a shaft (77) releasably connected to a pinion (78) meshing the pinion 21. Rotation of screw (83) moves the shaft (77) axially to disengage the shaft from the pinion (83) and permit towing of the vehicle.

Abstract: 1277010 Valves ROVER CO Ltd 27 Nov 1969 [19 Dec 1968] 60289/68 Heading F2V [Also in Division F1] In a fuel pump for a gas turbine burner comprising a rotor 1 having three axial cylinders 2 in which pistons are reciprocated by an inclined cam plate, part of the pumped fuel is spilled via a passage 6 and three centrifugally actuated valves. Fuel passes to the passage 6 via parts 4 in each cylinder and a valve plate having arcuate inlet and outlet parts. Two of the valves are identical and comprise valve seatings 7, each having a central stepped through bore, and halfball valve members 9 tensioned to close the bore by leaf springs 10. Fuel spills from the passage 6 when the centrifugal force in the members 9 overcomes the springs, which are arranged to allow one valve to open first. In the third valve a cylindrical body 21 is positioned in the stepped through bore, the body having a flat side face at the end adjacent the half-ball member and an annular collar 22 at its other end. The length of the body is such that whilst the bore is closed by the half-ball the collar 22 is clear of the inner end of the seating 23 its other end abutting the halfball. As the rotational speed of the rotor is increased the half-ball uncovers the bore and fuel may be spilled through the passage between the flat side face on the body 21 and the through bore in the valve seat, until the half-ball is fully displaced against its spring; at this point the collar 22 abuts the inner end of the seating 23 to stop the flow. The third valve is actuated before either of the other valves.
