Abstract: 1,252,941. Mowers. A. F. HYDRAULICS Ltd. 7 Jan., 1969 [12 Jan., 1968; 8 Nov., 1968], Nos. 1944/68 and 1038/69. Heading A1F. [Also in Divisions B4, B5, E1, and Fl] A transducer, operating the blades of a grass cutting machine, comprises a piston 14, 16, 18 reciprocated in a cylinder 10 by an oscillating fluid pressure supply 28 applied to one or both cylinder chambers 24, 26 containing opposed piston pressure faces 20, 22, the transducer being cooled by arranging for part of the pressure supply to flow from one chamber to the other and thence to a tank 40. In the embodiment shown, the supply 28 acts in the chamber 24 against fluid filling the chamber 26, which fluid acts as a spring. When the piston moves to the left grooves 70 therein register with a port 37 to allow a quantity of fluid to pass from the. chamber 26 to the tank 40. Replenishing fluid enters the chamber 26 through a conduit 74 connected to the chamber 24. A valve 76 in the conduit 74 has an open position for stopping the piston oscillations and a closed position allowing a restricted flow of replenishing fluid. If the piston oscillations migrate to the right, alignment of a circumferential groove 52 with a port 62 causes high pressure fluid in an accumulator 66 to enter the chamber 26 via piston passages 58, 60. Leakage past the piston seals is collected in grooves 35, 39 and returned to the tank 40. In a second embodiment, Fig. 3 (not shown) the spring chamber (123) is defined by a flexible rubber sleeve 126 exteriorly loaded by a fixed volume of gas. The opposed piston faces (115, 118) of this embodiment are disposed in respective chambers (120, 123) on opposite sides of a central partition 124 containing passages (152, 158, 160) which register with grooves (154, 162) in the piston (112) during its reciprocation and thus allow the cooling flow. If both chambers are fed with oscillating fluid, the oscillations in each chamber are arranged to be in anti-phase relationship.
