Abstract:
A weather strip is provided to increase lubricating strength and mounting strength by mounting in the lubricating oil-filled state. The weather strip(1) is installed on a joint(P) of a body side composed of an inner panel(3) and an outer panel(5), and composed of a body portion(7) provided with ribs(L1,L2,L3) and a hollow cushion portion(9) formed on one side of the body, wherein two primary ribs and two secondary ribs are connected with each other to form a space filled with lubricating oil, and a fracture groove is formed forward on a connection between the primary rib and the secondary rib to be torn by the joint of the body side to leak out the lubricating oil.
Abstract:
The invention relates to a drive force for feeding extinguishing medium into at least one spray head (2, 3) for extinguishing fire, the drive source comprising a liquid source (5) including liquid and a gas source (9) including gas, mixing means for mixing the liquid of the liquid source (5) and the gas of the gas source (9), and transportation means (1) for leading the liquid and the gas to the spray head in such a manner that an extinguishing medium including a liquid component and a gas component is led to the spray head. In order for the drive source to enable a controlled dosage of gas to be obtained in the liquid and preferably a substantially even and small droplet size for a substantially long time during the extinguishing process, the drive source is characterized in that the mixing means comprise a cylinder piston apparatus (50) including a first piston (12) arranged in a first cylinder (10) and a second piston (13) arranged in a second cylinder (11), the cylinder piston apparatus being arranged at each stroke to simultaneously provide both liquid and gas to the transportation means (1).
Abstract:
PURPOSE: A testing device for performance of an exhaust unit is provided to detect an optimum exhaust system through a principle test by realizing effect by temperature and effect by fluid. CONSTITUTION: A tester drives a motor(11) for rotating a fan(12) of blowing air to a pipe(3). The tester turns on a burner(13) to generate heat in the pipe. A cyclo-sound pressure identified with right frequency is transferred to the pipe through a speaker(4) by using a signal converter(8) and an amplifier(7). In an identified state with traveling state of a vehicle, change in sound pressure caused by air blow in the pipe is measured through a first sound pressure detect unit before a first muffler(1). Air direction in the pipe is detected by an air direction sensor(17) for transferring a data to a controller(18). Temperature in the pipe is detected by a temperature sensor(16) for transferring data to the controller. After detecting initial values before passing through the muffler, change in the sound pressure is detected in a second sound pressure detect unit(15) after passing through the first muffler and a second muffler(2). Then, a computer(10) decides performances of the mufflers by comparing the initial values and the values after passing through the mufflers.
Abstract:
PURPOSE: A resonator performance testing device of a car is provided to reduce time waste due to a repeat test by manufacturing a pipe of an intake device identical to that of a real car to test the resonator on the pipe to simplify the test. CONSTITUTION: A resonator performance testing device of the car includes a first pipe(10) having the same length as a total length of a cylinder head, an intake manifold, a surge tank and a throttle body of a real car and a second pipe(20) communicating with the first piping and having an air filter(21) and a plurality of resonators(22,23) on a pipe path. The first pipe has a speaker system(30) for discharging engine noise at an inlet side. The second pipe has an anechoic device(40) mounted at an outlet side. Microphones(51,52,53) electrically connected with a noise analyzer(50) are mounted at a prescribed position of the first and second pipes.
