摘要:
A fuel vapor recovery system has a fuel tank, an adsorbent canister, a separator capable of separating fuel vapor from air, and a negative pressure supplier applying negative pressure to the adsorbent canister in order to remove the fuel vapor from the adsorbent canister. The separator has a housing and a separation membrane. The separation membrane divides an inner space of the housing into a receiving chamber and a permeation chamber and is configured to allow the fuel vapor to pass therethrough. The separator is connected with the fuel tank such that the fuel tank is fluidly connected with the receiving chamber. The negative pressure supplier is fluidly connected with the adsorbent canister via the permeation chamber. When the negative pressure supplier applies negative pressure to the adsorbent canister, purge gas flows from the adsorbent canister into the fuel tank via the permeation chamber.

An apparatus for checking leakage from a fuel vapor processing apparatus includes an interrupting device capable of interrupting communication between a canister and a fuel tank when a pressure within the canister is negative and a pressure within the fuel tank is positive. A first pressure detecting device can detect the pressure within the canister or its equivalent. A second pressure detecting device can detect the pressure within the fuel tank or its equivalent.

A fuel vapor processor has a fuel tank, a canister, a vapor pipe, a recovery pipe, an air pipe, a suction device, a vapor pipe valve, an air pipe valve, and a pressure regulator. The vapor pipe leads fuel vapor generated in the fuel tank to the canister for trapping the fuel vapor in the canister. The recovery pipe recoveries the fuel vapor desorbed from the canister into the fuel tank. The air pipe communicates the canister with the atmosphere. The suction device is disposed on the recovery pipe for desorbing the fuel vapor trapped in the canister. The pressure regulator is communicated with the air pipe between the air pipe valve and the canister in order to allow gas flow from the atmosphere toward the canister. During desorption of the fuel vapor due to the suction device, the vapor pipe valve and the air pipe valve are closed, and negative pressure is kept in the canister such that the fuel vapor is desorbed from the canister and fresh air is led into the canister via the pressure regulator.

The present invention includes a first canister disposed within an intake air passage. The first canister communicates with a fuel tank via a second canister, so that a fuel vapor produced within the fuel tank can be purged by the second canister and further by the first canister. The second canister communicates with the intake air passage via a purge passage. The negative pressure within the intake air passage may be applied to the first and second canisters via the purge passage, so that the fuel vapor adsorbed by the first and second canisters can be desorbed or purged and can then be returned into the intake air passage.

A support structure for a display device includes a base member fixed to a rear surface of the display device, a support member which is fixed pivotably to the base member and supports the display device in a supporting position in an opened state where the display device is inclined at a predetermined angle and capable of being stored in a closed state, a holding member fixed to the base member including a regulation portion that regulates rotation of the support member beyond the supporting position, a pressure member that presses an end portion of the support member, and a compression coiled spring that urges the pressure member toward the support member. The pressure member includes a protruded portion having a triangular cross section, and inclined surfaces contacting with the support member while pressing the end portion when the support member rotates from the closed state to the opened state.
摘要:
A canister, for inhibiting a diffusion phenomenon in an adsorbent layer as much as possible and certainly adsorbing fed evaporated fuel to inhibit blow-by of the evaporated fuel into the atmosphere, is constituted by filling a first adsorbent layer of the canister with activated carbon A having a large evaporated fuel adsorption and a weak holding power, and filling a second and a third adsorbent layers with activated carbon B having an intermediate evaporated fuel adsorption and a weak holding power and therefore having characteristics that the residual amount of the low boiling point components in the evaporated fuel after purge is small, whereby after the high temperature standing of the canister, the discharge of the evaporated fuel into the atmosphere can be inhibited.

This invention relates to a rotary encoder for use in measuring the number of revolutions per minute or measuring the angular phase of a rotary shaft of a rotary machine. The encoder is provided with a fixed slit disc having slits therein, and a rotary slit disc disposed so as to be spaced from the fixed slit disc at a predetermined distance, having a plurality of slits arranged radially at regular angular intervals, and adapted to be rotated with the rotary shaft. The encoder is shipped to a user after the rotary slit disc has been fastened to the fixed slit disc on the part of the manufacturer.
