    摘要: A valve assembly is disclosed for controlling fluid flow in a first direction and a second direction. The valve assembly includes a housing for enclosing a substantially circular regulator assembly which extends diametrically across the housing. The regulator assembly comprises a hub portion which is positioned centrally within the housing and connecting members which extend radially toward a rim portion which is supported by the housing. The hub portion supports a disk-shaped substantially inflexible portion of the regulator assembly which extends over the connecting members to engage the rim portion and thereby prevent fluid flow in a reverse flow direction through the regulator assembly. The connecting members of the regulator assembly are adapted to flex and allow the disk portion to move off of the rim and thereby allow fluid flow through the valve in the first direction.

    摘要: An operational carrier for a wheel-type hay rake has an upper frame with one end for single point attachment to the draw bar of a towing vehicle. A lower frame is disposed beneath the upper frame and pivotally connected at one end to the upper frame. A first linkage is pivotally connected at one end to the upper frame and has an opposite end for attachment to the frame of the hay rake. The lower frame is provided with means for pivotally attaching an opposite end of the lower frame to the frame of the hay rake. Hydraulic means mounted on said upper frame has a piston rod connected to the lower frame for raising the lower frame to move the frame of the hay rake when said first linkage is connected to the frame of the hay rake in a substantially vertical direction from a raking position to a transport position.
