Problems solved by technology

[0003] In addition, currently, there is a device that guides the surplus fuel discharged from the pressure regulator that adjusts the pressure of the fuel supplied to the nozzle to the vicinity of the suction filter of the fuel pump through the return passage, but if there are many air bubbles in the surplus fuel, When the fuel pump sucks this fuel, the fuel supplied to the internal combustion engine will be interrupted by the air bubbles, causing the so-called gasping phenomenon of the internal combustion engine.

Embodiment approach 1

[0018] 1 is a cross-sectional view showing a state in which a fuel supply device for a vehicle (hereinafter referred to as a fuel supply device) according to Embodiment 1 of the present invention is installed inside a fuel tank of a motorcycle as a vehicle.

[0019] In FIG. 1 , a fuel supply device 1 according to Embodiment 1 of the present invention is fixed to an opening provided on the bottom 21 of a fuel tank 2 of a motorcycle with bolts 51 and 52 via a seal ring 3 and a mounting plate 4 . 22 on. Fuel 50 is stored in the fuel tank 2 up to a liquid level 501 . A discharge pipe 6 is installed on the fuel supply device 1, and the fuel in the fuel tank 2 sucked by the fuel pump through a suction filter (hereinafter simply referred to as a filter) 12 passes through the discharge pipe 6 to the future as described later. The fuel supply system of the illustrated internal combustion engine supplies.

Embodiment approach 2

[0034] 6 is a cross-sectional view of a fuel supply device according to Embodiment 2 of the present invention, and FIG. 7 is a cross-sectional view viewed from an arrow direction along line C-C thereof.

[0035] In this second embodiment, the chamber unit 100 has steam discharge passages 106 a , 106 b , and 106 c communicating with the filter housing chamber 103 . These steam discharge passages 106a, 106b, and 106c extend upward in FIG. 6 from the filter housing chamber 103, and open at their upper ends.

[0036] In addition, the surface of the partition wall 104 exposed in the filter housing chamber 103 is formed in a tapered shape inclined upward in FIG. 6 from the center portion through which the oil suction pipe 71 of the fuel pump 7 penetrates toward the edge portion. In addition, the edge portion 104a of the partition wall 104 is smoothly connected to the steam discharge passages 106a, 106b, and 106c. Therefore, the air bubbles mixed in the fuel in the filter housing ch...

Abstract

The invention relates to a multifunctional enzyme that can be derived from crustaceans or fish. The enzyme has at least one of a chymotrypsin, trypsin, elastase, collagenase and exo peptidase activity, and a molecular weight between about 20 kd and about 40 kd as determined by SDS PAGE. Preferably, the multifunctional enzyme has substantial anti cell-cell adhesion activity. Preferably, the multifunctional enzyme has substantial homology with the krill multifunctional enzyme. These enzymes are useful for treating viral infections such as herpes outbreaks, fungal, bacterial or parasitic infections, including the primary and secondary infections of leprosy, colitis, ulcers, hemorrhoids, corneal scarring, dental plaque, acne, cystic fibrosis, blood clots, wounds, immune disorders including autoimmune disease and cancer. Additionally, the invention relates to a method of purifying the multifunctional enzyme, and to a preparation of essentially purified multifunctional enzyme.

Description

technical field [0001] The present invention relates to a vehicle fuel supply device for supplying fuel from a fuel tank to a fuel supply system of an internal combustion engine installed in a vehicle such as a motorcycle. Background technique [0002] For vehicles, especially two-wheeled motorcycles, when the fuel remaining in the fuel tank is small, even if the liquid level of the fuel changes due to the acceleration and deceleration of the vehicle or the attitude changes, it is necessary to reliably supply the fuel without being affected by it. The pump sucks in fuel and supplies it to the fuel supply system. Currently, as an example of its correspondence, there is a fuel supply device for a vehicle in which a cup with an open top is mounted on the bottom of a fuel tank, and an opening having a diameter smaller than the inner diameter of the cup is provided in the fuel tank, through which the The main part of the fuel pump and the fuel suction filter are inserted into th...
