Abstract

1460664 Hydraulic lifting circuit MASCHINENFABRIK FAHR AG GOTTMADINGEN 23 Jan 1974 [2 Feb 1973] 03180/74 Heading A1F A hydraulic circuit Fig. 1 for controlling the height of an agricultural implement 5 associated with a self propelling, drawn or pushed agricultural machine 1 consists of the following parts serially connected: a lifting cylinder 6; a pressure reservoir 14; a non- return valve 15 having an adjustable pressure relief return valve 16 connected in parallel therewith for permitting feed-back of fluid; a multi-way valve 9; a pump 8; and a fluid reservoir 10. One embodiment Fig. 2 comprises a block 18 having various coplanar bores 19, 20, 26 and 27 therethrough, bore: 19 containing the non-return valve; 20 containing the pressure relief valve; 26 communicating with the multiway valve; and 27 communicating with the lifting cylinder 6. The communicating connections 28 and 29 are on the same face of the block 18, pressure reservoir 14 being flanged 30 onto the opposite face of block 18 and communicating with a through extension of the bore 27.
