摘要： In a pressure sensing device for a fuel tank, a mounting member for mounting a fuel pump is provided with a pressure detecting opening. A base member is fixed to the mounting member through a seal member. A pressure sensor is mounted on the base member. Accordingly, the installation to the fuel tank can be facilitated and the number of parts can be decreased, thereby increasing production efficiency.

摘要： A pressure difference detector for detecting a pressure difference between atmospheric pressure and a fuel system vapor pressure to be measured, includes a pressure dampening member 17a for dampening the flow of atmospheric air between an introducing inlet 11a and a reference pressure chamber 12 to limit the air flow rate to a value smaller than a leakage flow rate between the chamber and a fuel system vapor pressure introducing inlet 11b due to a leaking 0 ring seal. This prevents an erroneous judgment that the fuel system is leaking.

摘要： A compact pressure detecting apparatus comprising a pressure sensor unit, having a semiconductor pressure-detecting device provided with gauge resistance, integrated with a solenoid valve unit for controlling a channel of a measurement fluid into the body of the apparatus. The semiconductor pressure-detecting device partitioned a sensor vessel into a reference pressure chamber and a measurement fluid introduction chamber the measurement fluid introduction chamber can communicate with an environment outside of the pressure sensor unit the pressure-detecting device has a base with a through-hole, on which an electronic circuit and the pressure sensor are mounted. The pressure detecting apparatus also includes a solenoid valve unit; a port portion having a plunger storing portion with an opening at one end, a first intake channel for communicating the plunger storing portion with an environment outside of the solenoid valve unit which introduces a first measurement fluid, a second intake channel for communicating the plunger storing portion with an environment outside of the solenoid valve unit which introduces a second measurement fluid, and a discharge channel for communicating the plunger storing portion with the measurement fluid introduction chamber. The pressure sensor unit and the solenoid unit are integrated into one body by joining the base with the port portion so that the through-hole of the base communicates with the discharge channel of the port portion.

摘要： In a pressure sensing device, a sensor housing container is provided with a flange-like mounting portion to be attached to a medium container made of a thin plate by a bolt. The flange-like mounting portion has a mounting plane of said sensor housing container and is formed to have a great thickness enough to provide high rigidity. At the mounting plane, there are provided an opening through which a nipple of said pressure sensor protrudes from the sensor housing container and a concave plane on its periphery. A sealing member of elastic material is caused to intervene between the flange-like mounting portion and the medium container. The sealing member is integrally molded in a first space formed between an inner wall of the opening and an outer wall of the nipple and a second space communicating with the first space and formed by the concave plane when the sensor housing container is mounted on the medium container. Thus, a pressure sensing device can be obtained which does not require redundant components for reinforcement to be added to the medium container of a thin plate for housing a measuring pressure medium.
