A valve includes a valve axis extending in an axial direction, a valve housing, a ring that surrounds the valve axis, a seal, a spring for exerting a spring force, and a piston arranged in the valve housing. The valve housing includes a first valve housing opening through which a flow medium can pass. The ring is secured to the first valve housing opening. The seal is held on the valve housing by the ring. The piston is coaxial to the valve housing on the valve axis and axially faces the first valve housing opening. The piston is axially movable in the valve housing against the spring force, and the first valve housing opening can be closed by the piston.

A pressure control valve for gases and/or liquids comprising a first sealing body and a second sealing body for opening and closing a first flow path and a second flow path, respectively. The first and the second sealing bodies can be installed in an inflow for gases and/or liquids in order to define the first and the second flow paths therein. The first sealing body is guided in an axially movable fashion. The second sealing body is guided in an axially movable fashion within the first sealing body. The first sealing body is movable by a force in the effective direction from an outflow to an inflow from a closing position into an opening position in which the first flow path is opened. The second sealing body is movable by a force in the effective direction from the outflow to the inflow from a closing position into an opening position in which the second flow path is opened.

Pressure valve for a liquid comprising a housing with an inlet and an outlet for directing the liquid from the inlet through the housing to the outlet along a flow direction, wherein valve further comprises movable member which is movable in the housing towards and away from the outlet between a blocked position wherein the movable member blocks the outlet and an unblocked position wherein the movable member is moved away from the outlet in a direction opposite the flow direction.

Weapon simulators and components for a weapon simulator are provided. In particular, a lower receiver for a weapon simulator is provided. In preferred embodiments, the lower receiver comprises a first air pressure regulator contained within the lower receiver and a second air pressure regulator contained within the lower receiver and designed to supply a higher pressure compressed air than the first air pressure regulator. The first output of the first air pressure regulator controls the second output of the second air pressure regulator. The lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component.

The invention describes a pressure regulator for verifying the inflation of balloons of endotracheal cannulas or tubes, the regulator comprising: a housing with an inlet and an outlet in which an endotracheal cannula or tube connector that includes the balloon is coupled. The housing has a flow chamber and a pressure regulating chamber; a one-way valve mounted on the inlet; the housing also comprises a plurality of deflectors mounted in the flow chamber to reduce the velocity of the gaseous fluid. The regulator has a pressure-indicating piston mounted in a movable manner in the pressure-regulating chamber, which is visible to the user; a sealing piston operationally connected with the indicating piston and underneath same so that they both move simultaneously.

A device for regulating the pressure of a compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage; a mobile element biased by a main spring and carrying a shutter cooperating with a seat in the gas passage, the shutter and the seat forming a regulating valve, a shut-off valve with a shutter and a seat in the gas passage upstream of the regulating valve; an actuation assembly of the shut-off valve; wherein the shutter of the shut-off valve comprises a stem extending through the mobile element and the shutter of the element, for cooperating with the actuation assembly located in front of the element.

A pressure regulating and pressure relief valve, has a valve body defining an inlet port, outlet port, valve seat and pressure relief opening. A pressure regulating plug is displaced during a first portion of a motion from an open position, which provides a continuous flow path from the inlet port to the outlet port, to a closed position in which the plug is closed against the valve seat to obstruct the continuous flow path. A spring biases the plug to the open position. An actuation surface is exposed to a pressure at the outlet port that displaces the plug against the spring bias toward the closed position. Further displacement of the plug beyond the closed position during a second portion of the motion that is beyond a range of the first portion of the motion, opens a relief flow path from the outlet port through the pressure release opening.
