With Selective Motion For Plural Valve Actuator Patents (Class 137/636)
  • Patent number: 9561783
    Abstract: A braking apparatus for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve, and a collision avoidance controller. The solenoid valve selectively exerts the hydraulic pressure of brake fluid stored in an accumulator on a spool valve in the booster. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, emergency braking is achieved by installing the solenoid valve to selectively exert the hydraulic pressure on the spool valve, thus allowing an emergency avoidance braking system to be constructed with a minimum of equipment and facilitating the mountability of the braking apparatus in the vehicles.

  • Patent number: 7861742
    Abstract: A cartridge of a water supply valve that controls the flow rate and temperature of water without causing interference between flow rate control operation and temperature control operation of the valve. In the cartridge, a flow rate control knob (12) angularly moves forwards and rearwards and actuates a control lever (14) to open or close cold and hot water supply holes (1a and 1b). A temperature control knob (13) is coupled to the flow rate control knob (12), linearly moves leftwards and rightwards, and actuates the control lever (14) to control the opening ratios of the water supply holes. Thus, this cartridge does not change the existing temperature of water during flow rate control operation or change the existing flow rate of water during temperature control operation. This invention reduces the quantity of water to be unnecessarily wasted and, at the same time, prevents undesirable consumption of excessive energy.

    Abstract: A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice. The initial opening of the valve in an axial direction enables gas to flow through the pressurization orifice at a first flow rate. The full opening of the valve in the axial direction enables the gas to flow through the second valve at a second flow rate, which is much higher than the first flow rate. The controlled pressurization of the gas through the orifice delays the time during which the gas reaches full recompression. The valve may be further provided with a vent for venting pressurized gas away from a nominally closed top surface of the lower valve element.

  • Patent number: 5868166
    Abstract: A pressure regulating valve usable in combination with a hydraulic steering system has a spring mechanism axially disposed between a pair of axially aligned valve spools. Movement of the spring mechanism in a first direction resiliently moves one of the valve spools to a position for communicating an inlet port with a control port and regulating the pressure in the the control port so that the pressure is proportional to the degree of movement of the spring mechanism. Conversely, movement of the spring mechanism in a second direction resiliently moves the other valve spool to a position for communicating the inlet port with another control port and regulating the pressure in the other control port so that the pressure is proportional to the degree of movement of the spring mechanism.

    Abstract: A rubber valve plate is sandwiched between a stator and a cover. Ports in the stator for coupling to a vacuum source and vacuum motors are aligned with poppets molded in the valve plate. A manifold in the plate joins regions surrounding the valves to couple the vacuum source to all the valves. Openings in the cover plate allow a dome of each poppet to protrude. A rotary actuator adjacent the cover is configured to selectively engage the domes to actuate certain poppets which are moved against the stator to close the port to vacuum or are allowed to move toward the cover to connect the port to vacuum.

  • Patent number: 5305782
    Abstract: A pneumatic control valve system has a modulating valve and a piston. When the operator depresses the piston, pressure is communicated to a switching piston moving that piston to a switched position so that pressure is communicated to a switching outlet. The switching piston retains this switched position when the first piston is released. When the modulating valve is opened to communicate pressure to a work port, pressure is also communicated to the switching piston in order to move the switching piston back to its unswitched position whereat the switching outlet is vented. The switching piston allows the control of another function.

  • Patent number: 4955442
    Abstract: A vehicular steering mechanism of overly complex construction is known which displaces a left turn control valve or a right turn control valve through separated cams in response to the rotation of a steering wheel. The subject steering mechanism is simpler, more economical and more compact by including an input shaft and a single actuating cam which are conjointly rotatable away from a neutral position in either direction. The actuating cam defines a profiled guide slot of a substantially spiral shape, and a cam follower assembly is cooperatively associated therewith including a cam following roller wheel that is received in the profiled guide slot. The cam follower assembly includes a bellcrank supporting the roller wheel and indirectly connected to a left turn control valve and a right turn control valve. The vehicle is steered by the controlled rotation of the bellcrank and the subsequent displacement of the control valves and. The steering mechanism also includes an effective centering and stop assembly.

  • Patent number: 4911211
    Abstract: An apparatus and method for changing the antifreeze in a vehicle requires only a garden hose and opening of the radiator cap. Water from the hose is utilized to prime a conduit for siphoning used coolant from a side tank radiator and for refilling the radiator. By operating the vehicle with fresh water in the radiator, coolant remaining in the system is mixed with the water, and repeated drainings decrease the remaining used antifreeze by about one-half each time. After removal of the desired amount of antifreeze, new antifreeze may be placed in the radiator.
