摘要： An improved fifth wheel hitch for attaching a trailer to a towing vehicle. The hitch includes an outer box support frame having two rails for mounting the trailer hitch to the towing vehicle, a spherical bearing mounted in the frame having a ball joint, and a latch assembly affixed to the spherical bearing to allow the assembly to have two degrees of movement, and a head body. The latch assembly comprises a base plate, a jaw fixed at a first elevation, and a vertically displaceable jaw. A means are provided to raise the vertically displaceable jaw above the level of the fixed jaw to allow release of the king pin latch. When the jaws are coplanar they capture the kingpin of a trailer, and safely lock the trailer to the hitch.

摘要： FIG. 1 is a front isometric view of a valve component;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is right side view thereof;
FIG. 5 is a left side view thereof;
FIG. 6 is a top view thereof;
FIG. 7 is a bottom view thereof; and,
FIG. 8 is a cross sectional view taken along line 8-8 shown in FIG. 2.
The short dash-long dash broken lines shown in FIG. 2 represents the plane upon which the cross sectional view is taken and forms no part of the claimed design. The evenly spaced broken lines in the drawings represent portions of the valve component that form no part of the claimed design. The dot dash broken lines in the drawings represent a boundary of the claimed design. A non-limiting example application of the valve component is for use in a hydraulic valve of a shock absorber.
