摘要： A device for the surveillance of the pressure of a vehicle tire includes a pressure-sensitive device which senses the tire pressure and generates, in case of a pressure loss in the tire, a pressure change signal. A set member is actuated with this pressure change signal such that the signal member performs a stroke. A sensor tests the position of the set member and recognizes when the tire pressure is too low. A pressure-sensitive device (1) includes a check valve (9, 12), opening toward the pressure discharge port (3). The pressure at the pressure discharge port (3) can be blocked versus the tire pressure based on the check valve (9, 12). The invention device is suitable for furnishing a continuous signal up to the complete emptying of a tire.

摘要： The invention device monitors the pressure of a measurement chamber subjected to the pressure prevailing in a vehicle tire. A pressure-sensitive device scans the tire pressure with a pressure measurement member in a measurement chamber. In case of a tire-pressure drop, the tire pressure is used to actuate an auxiliary actuator (3, 24, 26). The auxiliary actuator genrates the regulating distance (s) dependent on a tire pressure drop below a pressure value required for an actuation of the actuator (13). The regulating distance (s) is recognizable by a sensor. The invention device is suitable for providing a permanent signal even in case of an absence of pressure in the measurement chamber (21).

摘要： A relay valve device having a first control surface and a second control surface. A shut-off device is located in the line feeding the control pressure into the second control surface throughout the period in which a signal pressure is present, and connecting the second control surface to atmosphere at other times. Thus, the relay valve device releases a greater pressure into a load circuit when actuated during effectiveness of the signal pressure than while the signal pressure is not effective. The shut-off device having a pressure relief valve with a switch-off device so that when the signal pressure is effective, the switch-off device switches OFF the pressure relief function of the pressure relief valve and so that when the signal pressure is not effective, the pressure relief valve is opened as long as the control pressure remains below the relief pressure and is closed when the control pressure moves above the relief pressure.

摘要： An apparatus is furnished for sensing the tire pressure and for generating a signal by way of an actuator. If the tire pressure drops below the predetermined reference tire pressure, then this is signalled immediately and instantly within a relatively small pressure tolerance threshold. The pressure sensitive device 1 includes a valve device 7. The valve device 7 connects the tire pressure, applied to the actuator 4 and acting against the force of the compression spring 6, to the atmosphere if the tire pressure drops below a predetermined reference tire pressure. The apparatus is suitable for generating a permanent signal, even in case no further pressure remains in a tire.

摘要： A valve including a housing in which is disposed a relay piston. The relay piston has an upper control surface adjacent a control chamber leading to a control connection. The underside of the relay piston is in communication with a reaction chamber leading to a working pressure connection. An outlet valve seat is formed on the lower extremity of the relay piston. A multistage hollow graduated piston disposed within a graduated bore formed in the housing. The graduated piston has a tapered edge extending downwardly to form an inlet valve seat. A hollow valve element is cooperatively associated with the inlet and outlet valve seats to form inlet and outlet valves. The underside of the graduated piston a reaction chamber which is connected to a second control pressure connection. A supply pressure connection is connected to an annular chamber which is in communication with the inlet valve so the working pressure is gradually increased in steps until a predetermined pressure value representing an emergency situation is exceeded which causes the working pressure to immediately rise to the full pressure value of the supply pressure.

摘要： A load-controlled fluid pressure regulating valve device for tractor-trailer type vehicle brake systems which combines in a single housing a unitary piston valve assemblage capable of performing the functions of a relay valve device and a regulating valve device. The unitary valve assemblage is acted upon under normal circumstances by the brake valve control fluid pressure and is further arranged for direct actuation by an emergency piston in the event of fluid pressure loss in the trailer supply line due to uncoupling or to a broken pipe. The valve assemblage is adjustably positioned in accordance with the vehicle load condition such that the relay valve function reflects the load regulating control valve.

摘要： A process for preventing the formation of polymeric by-products during the production of Diels-Alder adducts is improved by the addition of NO or of a compound splitting off NO in situ, as a polymerization inhibitor. This process is especially effective for preventing the formation of polymeric by-products in the manufacture of 5-vinylnorbornene-2. In a tubular reactor, when observing narrow temperature and pressure ranges, a high selectivity is obtained in the production of this adduct.

摘要： The invention relates to a load-dependent brake pressure system for a pneumatically activated motor vehicle and/or motor vehicle trailer brake apparatus with an entrance device having an initial entrance phase in which the full control pressure is delivered to the cylinders of the wheel brakes. In an emergency situation, the supply pressure which is available on the vehicle must be able to be conveyed in a graduated and controlled manner as the brake pressure is applied to the wheel brakes. The present load-dependent brake pressure system which, in an emergency situation, makes possible the application of brake pressures which are higher than that corresponding to the control ratio up to the available delivery pressure, includes an entrance valve and piston, a control valve, a brake control piston, a relay valve, auxiliary valves, a control, delivery, brake pressure connections and chambers, and a valve tappet for controlling brake pressures in multiple phases.
