    Abstract: Systems and methods for reporting a position of an air-over-hydraulic road treatment element use pneumatically activated switches triggered by pilot air for moving the road treatment element. Switch activation electrical signals are used to determine whether the road treatment element is in an engaged configuration or a disengaged configuration. If the switch activation electrical signals indicate the engaged configuration, an engaged configuration electric signal can be maintained until the switch activation electrical signals indicate the disengaged configuration. Conversely, if the switch activation electrical signals indicate the disengaged configuration, a disengaged configuration electric signal can be maintained until the switch activation electrical signals indicate the engaged configuration.

  • Patent number: 9062798
    Abstract: A pressure regulating device has a pressure regulating valve with a valve casing and a regulating unit which is movable relative to the former. The regulating unit contains an actuation element which may be moved by a control pressure, and two first and second closing members, each spring-biased in a closed position, which may be switched by the actuation element. The connection between a primary port and a secondary port is controlled by the first closing member. Fixed immovably to the actuation element is a restrictor element which is moved into a restriction position when the actuation element is so positioned that the first closing member is normally moved into its closed position. If, because of a fault, the first closing member is not moved into the closed position, only a very small amount of pressure medium flows to the secondary port, so that consequential damage may be avoided.

  • Publication number: 20120067444
    Abstract: A contracted portion having an axial length is formed in the spool hole and a large diameter portion having an axial length is formed in the spool within the spool such that an annular gap is formed there-between. A valve body closes an opening portion of the spool hole. When the valve body is lifted, one of an air pressure source and a drain is connected to an air spring passage via the annular gap. When the spool retreats from the valve body, the other of the air pressure source and the drain is connected to the air spring passage via the annular gap. By setting the lengths at different values, different flow rate characteristics are realized when supplying compressed air to an air spring and discharging air from the air spring.

  • Patent number: 7959042
    Abstract: A metering valve used with a pressurized dispensing container, the metering valve has a valve stem assembly that slides co-axially within an annular metering chamber that surrounds the valve stem assembly and forms a substantially cylindrical chamber body. The metering valve also has an outer seal at the top of the cylindrical chamber body and an inner seal at the bottom of the cylindrical chamber body. The valve stem assembly has an outlet and an associated passage that is above the line of the outer seal when the metering valve is at rest, and is below the line of the outer seal when the metering valve is actuated, thereby creating a dispensing passage for the metering chamber's contents. The valve stem assembly has an inlet and an associated passage that is above the line of the inner seal when the metering valve is at rest, and is below the line of the inner seal when the metering valve is actuated.

    Abstract: A pressure washer wand having first and second valves that can be opened in a predetermined or user-adjustable manner through movement of a trigger. In one form, the first and second valves are opened sequentially in response to movement of a trigger to transition from a no-flow condition to a relatively low pressure flow and thereafter to a relatively high pressure flow. In another form, the sequencing of the valves can be changed such that only the first valve, which provides a relatively low pressure flow, is opened in response to movement of the trigger. A pressure washing system having the pressure washer wand is also provided.

    Abstract: A coupling (110) comprising a pair of female couplers (116) each independently movable within a respective housing bore (114) among an operating position, a release position, and a coupling position. When a female coupler (116) is moved to the coupling position, a stop member (136) moves the plunger of a pressure relief valve (124) to an open position to allow fluid to be released from the female coupler (116) prior to coupling a male coupler thereto. A cam member (126), which is used to move the respective female coupler (116) from the operating position to the release position, can move away from the plunger when the female coupler (116) is in the coupling position as the pressure relief valve (124) is held open by the stop member (136).

  • Patent number: 7455075
    Abstract: A servo valve has a miniature force motor embedded in a main fluid chamber to directly operate between two nozzles to generate a differential pressure in two ports. The miniature force motor includes two disc ring-shaped magnets in opposing magnetic orientation, an armature base and poppet ends of magnetic material coupled to an armature shaft having pilot ends that interface to form the pilot stage valves at each armature shaft end. The armature shaft extends through a center hole in the magnets, armature base, and the poppet ends and engages bearing elements at each end allowing lateral armature motion. Two elastic members provide restoring forces to the armature assembly. Guide/stops have shaped magnetic surfaces to control the magnetic path and to linearize the force versus stroke and to increase the proportional stroke of the armature.

    Abstract: The present invention relates to the field of units for hydraulic pilot control of directional-control valves used in the fabrication of mobile vehicles and particularly relates to a hydraulic pilot control with an oscillation damping system. Connections are provided among the chambers in the pilot control unit to provide a damping effect in the actuation stroke, thereby preventing any oscillation: the provision of such connections among the chambers has the function of preventing air stagnation; this arrangement prevents any undamped behavior due to incomplete filling upon installation or to air transported in the hydraulic fluid.

The outer ring (4) is stationary relative to the valve housing, while the inner ring (6) may be displaced in the circumferential direction by means of a rotatable handle, whereby a greater or smaller overlap between the recesses may be provided. The maximum flow amount may hereby be set manually.
