Title: In-tank type pump
Inventor: MATSUDA TAKASHI
IPC: F04D13/06
Filed: 1987-04-17
Abstract: PURPOSE:To damp a pulsation propagated in fuel to prevent unpleasant noise by providing an annular groove in a rubber-mount. CONSTITUTION:While the pump runs, a pulsation is generated by the rotation of an impeller 20. The pulsation propagated to a discharge side is absorbed and damped by a fuel hose and fuel filter. On the other hand, the pulsation propagated to an inlet side propagates through an inlet port 17, a fuel-passage 119B of an end-cover 119, and an inlet port 119A reaches a terminal 123E of an annular groove 123D in a rubber-mount 123, and propagates to a puddle 123D after passing through the annular groove 123D. However, since the rubbermount 123 is made of elastic material such as rubber, etc., the pulsation is absorbed and damped while propagating through the annular groove 123D. As a result, the pulsation passes through a filter 24, and is not propagated to fuel in a fuel tank, and thus, no resonance is generated.

Filed: 1994-05-10
Abstract: PURPOSE:To avoid stop of all communication by providing a bypass relay to a transmission line of each station and short-circuiting an input and an output of the station side so as to exclude the effect of an abnormality occurred in one station onto other stations through a token ring communication line. CONSTITUTION:When a transmission disable state is caused in a communication program of each station, each station drives a bypass relay unit 1, and relay contacts a, b of the unit 1 short-circuit input and output of a line side and relay contacts c, d short-circuit input and output of a station side to form a closed loop. A host MPU writes self-diagnosis data to a RAM 4 for the transmission. Transmission data are looped back at bypass relay contacts c, d via a communication LSI 2 and a MODEM 3 and stored once in the RAM 4 through the MODEM 3 and the communication LSI 2 again and then the host MPU compares transmission and reception data. When any abnormality takes place in this case, it is discriminated as an abnormality of a concerned station to connect a bypass and when all equipments are not abnormal, it is discriminated that the cause resides in other stations, and bypassing is released and a channel is connected again to disconnect surely an abnormal station.
