Abstract

1372659 Hydraulic control circuits E WEBER, [trading as EMIL WEBER FABRIK FUR OLHYDRAULIK] 18 May 1973 [18 May 1972] 23904/73 Heading F1P In an arrangement for tilting the cab of a motor vehicle by a ram 1, a pin 40, which locks the cab in the lowered position, is withdrawn when pressure fluid is supplied to raise the cab. To raise the cab a valve 9 is moved to the left and fluid passes the through a line 6 to a chamber 29. Since a line 30 is closed by a valve 31 a piston 24 is moved to the right withdrawing the pin 40. This opens a line 32 so that fluid can extend the ram 1 by passing through line 6, valve 17 and a further line 6. To retract the ram 1 the valve 9 is moved to the position shown and fluid is supplied through a line 15 to a chamber 14. Pressure in the line 15 opens a check valve 7 so that fluid is returned from the chamber 5 through line 6, valve 7, valves 8 and 31 and chamber 29. Non-return valves 17, 7 hold the cab in any position when there is no pressure in line 15. When the cab is nearly completely lowered a pin 18 on the piston 2 pushes a member 19 which opens non-return valve 17. Application No. 10893/73, is referred to.
