摘要： A choke valve control system includes a choke-operating lever for opening and closing a choke valve of a carburetor, a choke spring for biasing the valve in an opening direction, and a damper for controlling the opening motion of the valve to a lower speed, when the choke valve is opened from its fully closed position by a biasing force of the choke spring. The choke-operating lever, the choke spring and the damper are connected to the choke valve of the carburetor. In this choke valve control system, the damper includes a damper housing, a rotor, and a damper oil which is accommodated in a sealed manner in the damper housing and applies a viscosity resistance to the rotation of the rotor, which resistance increases as the viscosity increases with decreasing temperature. Thus, the time required for opening the choke valve can be controlled in accordance with the level of the environmental temperature of an engine, thereby providing the stabilization of the warming operation of the engine and a reduction in fuel consumption.

摘要： An engine starting system for an internal combustion engine. The starting system includes a starter switch electrically connected between a battery and a starter motor for the engine, and a choke valve disposed in an air intake of an air/fuel-mixing device for the engine. The choke valve moves in response to a solenoid actuator. The solenoid actuator is electrically connected to the starter motor and a temperature switch. When starting the engine below a threshold temperature, the starter switch and temperature switch close such that the battery powers the starter motor and solenoid actuator. The energized solenoid actuator moves the choke valve to a closed position to enrich the air/fuel mixture. Above a certain threshold temperature, the temperature switch interrupts the power to the solenoid actuator.

摘要： The present invention provides flow-through humidifier device having a frame assembly adapted to be secured onto an air supply duct and having a back wall with an air inlet opening, two side walls, one with an air outlet opening, top and bottom walls and a front cover wall, an evaporator assembly including a pad, a water supply member and a water drain member to supply unfiltered water at standard city pressure to and collect any excess of water from the pad member respectively. The water supply member includes a valve controlled by an air temperature electronic controller. The latter is electrically connected to a temperature sensor sensing the temperature of the air flowing and timely pulses the valve to open when the air temperature is above a pre-determined set temperature and allow for water to humidify the pad. The top and bottom walls of the frame assembly are preferably a mirror image of each other such that the humidifier can be mounted in either an upright or an upside down orientation depending on the right or left hand side desired position of the air outlet opening respectively.

摘要： An engine starting system that includes a power source, an electromagnetic coil and core, and a choke valve disposed in an air intake of an air/fuel-mixing device of an internal combustion engine. At the time of starting the engine, the power source outputs an electrical signal to an electromagnetic coil and core, inducing a magnetic field from the electromagnetic coil and the core. The magnetic field from the core moves the choke valve toward a substantially closed position that enriches an intake mixture of fuel and air to the engine during starting. In one embodiment, the power source includes a moving magnet that interacts with a stator coil to provide the electrical signal to the electromagnetic coil. In another embodiment, the closing of a starter switch allows a battery to provide the electrical power to the electromagnetic coil.

摘要： A temperature compensator for a pressure splitter control chamber has two members which have different thermal expansion rates, and the dimensional changes in these two members caused by temperature change affect the pressure inside the control chamber. The compensator is normally designed so that the control chamber pressure is essentially constant with temperature change, but can be designed to increase or decrease the effect of temperature change on the pressure. This temperature compensator is especially useful in a control chamber used with a pressure splitter which is used as a carburetor compensator. The resulting temperature compensated control chamber allows the pressure splitter to easily be set for use with carburetors jetted for different base altitudes.

摘要： A variable venturi carburetor for a combustion engine has an uprighted cup-shaped piston head which forms an integral part of a venturi within a fuel-and-air mixing passage carried by a carburetor body, and a needle that projects rigidly downward from the head into a fuel feed passage. The position of the piston head controls air flow by adjusting the air flow cross-section of the variable venturi, and the needle simultaneously controls fuel flow into the fuel-and-air mixing passage at the venturi via obstruction of the fuel feed passage. The piston head and needle move in unison by a flexible diaphragm engaged to and disposed above the head. An atmospheric chamber is defined below the diaphragm and a vacuum chamber is defined generally above the diaphragm. A vacuum passage extends through the bottom of the head communicating between the fuel-and-air mixing passage at the venturi and the vacuum chamber. As vacuum at the venturi increases, the volume of the vacuum chamber decreases and the flexing diaphragm moves the head partially out of the fuel-and-air mixing passage until a balance of forces between the vacuum draw and the resilient compression of a spring disposed within the vacuum chamber and which biases the head into the passage is reached. During cold engine starts, cold idling, and cold acceleration, a cold engine priming device sensing the temperature of the engine and delivers additional fuel into the fuel-and-air mixing passage from a fuel chamber when the engine is below a pre-set value.
