  • Patent number: 11703145
    Abstract: Fluid damped check valves are described herein. A representative check valve includes a piston assembly movably positioned within a housing. The housing can include a flow chamber, a damping chamber containing a damping fluid, and a leak chamber fluidly coupled between the flow chamber and the damping chamber. The piston assembly can include a poppet positioned in the flow chamber, and a flange positioned in the damping chamber. In operation, the piston assembly is movable between (i) a closed position in which the poppet sealingly engages the housing to at least inhibit fluid flow through the flow chamber and (ii) an open position in which the poppet disengages from the housing and permits fluid flow through the flow chamber. When the piston assembly moves between the open and closed positions, the flange moves through the damping fluid in the damping chamber to slow the movement of the poppet.

A pressure control apparatus includes: a body having an opening portion penetrating a wall portion which demarcates a spool hole; a spool valve that is disposed displaceably in the spool hole; a plate-shaped retainer disposed at one end side of the spool valve in an axial direction in the spool hole; and an elastic member 6 disposed between the spool valve in the spool hole and the retainer. The retainer has a wide portion and a narrow portion. The opening portion has a first opening portion that allows the retainer to pass through and a second opening portion that inhibits the retainer from passing through.
