  • Patent number: 11248502
    Abstract: A supply passage extends through an inner sleeve in a radial direction and conducts hydraulic oil received from a hydraulic oil supply source. An axial passage is located between an outer sleeve and the inner sleeve and extends in an axial direction. The supply passage opens to one end portion of the axial passage while another end portion of the axial passage is configured to connect with a valve timing adjustment device. A supply check valve is installed in the axial passage and is located on a radial side of the supply passage where a radially outer side of the inner sleeve is placed. The supply check valve enables a flow of the hydraulic oil from the supply passage toward the axial passage and limits a flow of the hydraulic oil from the axial passage toward the supply passage.

  • Patent number: 7033166
    Abstract: The present invention is to provide a valve with a safety mechanism for diverting reverse gas flow being mountable in a gas lighter wherein a shoulder is formed around a mouth proximate a forward opening of a sleeve and is spaced apart from the forward opening by a predetermined gap when an actuation member is not pressed, the actuation member is pressed to lift a leakproof nut at a bottom of the mouth for opening a bottom hole of a seat to permit gas to flow into the valve, the shoulder then contacts the forward opening for blocking gas flow and direct the gas flow to a nozzle through a hose for ignition. Thus, after the actuation member being released, the gas remaining in the hose will flow back and leak through the gap and the forward opening to the outside because the gas pressure in the hose is larger than the outside pressure.

  • Patent number: 6386218
    Abstract: A solenoid operated exhaust bleed type pressure control valve assembly providing a proportional pressure control signal over the full range of solenoid operating current. A poppet valve member is connected to the solenoid armature and closes against a valve seat in the control signal port pressure chamber to prevent flow through the valve seat to the exhaust (bleed) ports. This results in very low or reduced leakage at minimum pressures. The poppet valve contacts a projection on a spool valve for effecting concurrent movement therewith for valving a supply pressure port in the control signal pressure chamber. In the normally closed version of the valve assembly, the poppet delays the spool opening of the inlet or supply port until solenoid current has reached about Five to Twenty Percent (5-20%) of maximum. In the normally open version, the spool is delayed in closing the supply inlet port until solenoid current reaches about Eighty to One Hundred Percent (80-100%) of maximum.
