Title: Hydraulic suspension arrangement
Inventor: GARRISON HAROLD K
IPC: A01D41/14
Filed: 1983-10-18
Abstract: A hydraulic suspension arrangement for an agricultural appliance has a gas/oil accumulator (42) and oil in the flow path between the accumulator (42) and head of the lifting cylinders (18) is held under a subsiding initial load which is so selected that the head (14) can slide over ground obstacles and be raised by these. It is intended that this be possible expending less force. A separate cylinder (54) with a floating piston (56) is arranged in the flow path from the accumulator (42) to the lifting cylinders (18) in such a way that with less holding force of the accumulator (42) than the force exerted on the opposite side of the floating piston (56) by the fluid between the piston (56) and the lifting cylinders (18) the floating piston (56) bears on one end (58) of the cylinder (54) and thereby supplies an unyielding holding force for the head (14) at its preselected working height. If contact is made with a ground obstacle, part of the force required in order to raise the head (14) over the obstacle is provided by the compressed gas in the accumulator (42). The auxiliary force provided by the accumulator (42) can be adjusted by a discharge valve (66), which lies in a secondary line (64) bypassing the cylinder (54) with the floating piston (56). <IMAGE>

Title: Maintenance-free plastic ball valve for preventing backflow in pipe conduits
IPC: F16K27/02
Filed: 1984-02-29
Abstract: After a certain time in operation, fittings of relatively large nominal diameter, comprising cast-iron basic bodies, having metal seating surfaces and installed in pipe conduits to prevent backflow, exhibit encrustations and these lead to faults in their operation. The aim of the present invention is to avoid disadvantages of this kind. A basic body constructed from tubular plastic parts is constructed to have a common inlet for the liquid and two outlets of different sizes. The smaller outlet and the inlet correspond to the specified nominal diameter of the fitting. In the tubular part with the larger diameter there is a freely movable sinking ball which comes to rest automatically on the sealing seating surface formed in the inlet of the fitting and thus prevents backflow. The upper end of the ball guide is closed. There are appropriate fixing means at the inlet and outlet of the fitting for installation in pipe conduits. To increase pressure stability, a steel-reinforced rigid-foam casing is produced around the basic body.
