Abstract
A magnetic check valve 101 comprises two passages 111, 112 of different diameter forming valve seat 114, a valve member 115 maybe biased against seat 114 by spring 117 and held there by magnetism. A choke passage 110, which connects the valve interior to its exterior, is located adjacent seat 114. Member 115 may comprise cone 1151 carried by disc 1152 and seat 114 may comprise annular magnet 116 with a central aperture. Choke passage 110 may be curved with a complementary curve formed on member 115 (fig. 5a). Two magnetic closure members (615a, 615b, fig. 6), with respective seats (614) and choke passages (610) may be joined by a spring (617). Spring 117 may be seated against an adjustable screw 118. A doorstop for vehicles, comprising a sealed fluid chamber divided into two (A, B, fig. 4) by a piston (403) driven externally by a pin (402), has two opposing magnetic check valves (300) which allow fluid communication between chambers (A, B) when the pressure in either chamber exceeds a set threshold. The piston may be mounted to slide (fig. 4) or pivot (fig. 7). Pin (704, figs. 8a and b) may be driven by a rod (703) connected to a crank pin (701) which is connected to a hinge pin (700) or it may be driven by rotation about a screw thread located either inside (fig. 9a) or outside (fig. 9b) the doorstop.
