A vane pump in which a lubricating oil from an oil supply pipe 12 is supplied to a pump chamber 2A through an axial direction oil supply hole 11a of an oil supply passage 11, a diameter direction oil supply hole 11b, and an axial direction oil supply groove 11c. A gas passage 13 includes a diameter direction gas hole 13a and an axial direction gas groove 13b, and the diameter direction gas hole 13a is made to communicate with the axial direction gas groove 13b when the diameter direction oil supply hole 11b is made to communicate with the axial direction oil supply groove 11c.
摘要:
A vane pump 1 has a pump chamber 2A through an axial direction oil supply hole 11a, a diameter direction oil supply hole 11b, and an axial direction oil supply groove 11c of an oil supply passage 11. A gas passage 13 contains a gas groove 13a whose one end is made to communicate with an outer space, the gas groove 13a being formed on an outer peripheral surface of a shaft part 3B of a rotor 3, and the other end of this gas groove is made to intermittently overlappingly communicate with the axial direction oil supply groove 11c by a rotation of the rotor.

A lubricating oil to be supplied to a vane pump 1 is supplied to a pump chamber 2A through an axial direction oil supply hole 11a, a diameter direction oil supply hole 11b, and an axial direction oil supply groove 11c of an oil supply passage 11. A gas passage 13 is comprised of a gas groove 13a whose one end is made to communicate with an outer space, the gas groove 13a being formed on an outer peripheral surface of a shaft part 3B of a rotor 3, and the other end of this gas groove is made to intermittently overlappingly communicate with the axial direction oil supply groove 11c by a rotation of the rotor.Clogging does not easily occur as compared with a case where the gas passage 13 is comprised of a through-hole as a conventional apparatus since the gas passage is comprised of the groove-shaped gas groove 13a, thus enabling to reduce a passage area of the gas passage. Hence, the air is prevented from being sucked in the pump chamber from the gas passage as much as possible, thereby enabling to prevent the increase of engine driving torque.

A disc brake assembly which includes a disc rotor, a mounting member having arm portions in which a pair of grooves extending toward the axial direction of the disc rotor are provided therein, a pair of brake pads disposed to both sides of the disc rotor, at least one of the brake pads having a pair of ear portions which are outwardly projected in the rotational direction of the disc rotor and which are fitted into the grooves of the mounting member so as to be slidably supported on the mounting member, a caliper member slidably supported on the mounting member so as to be movable in an axial direction of the disc rotor and pressing each of the brake pads against faces of the disc rotor, respectively and pad clips engaged with the arm portions of the mounting member so as to cover faces of the grooves and being provided with a first elastic member which is formed on the pad clip in a body and which always outwardly urges the brake pad with a low load in the diametrical direction of the disc rotor through the ear portion and a second elastic member which is formed on the pad clip in a body and which is adjacent to the first elastic member so as to be able to receive the ear portion of the brake pad with high load, respectively. According to this improved disc brake assembly, it is able to slidably support the brake pad on the mounting member without a play in the diametrical direction of the disc rotor while preventing the generation of the dragging phenomenon.

A lubricating oil from an oil supply pipe 12 is supplied to a pump chamber 2A through an axial direction oil supply hole 11a of an oil supply passage 11, a diameter direction oil supply hole 11b, and an axial direction oil supply groove 11c. A gas passage 13 includes a diameter direction gas hole 13a and an axial direction gas groove 13b, and the diameter direction gas hole 13a is made to communicate with the axial direction gas groove 13b when the diameter direction oil supply hole 11b is made to communicate with the axial direction oil supply groove 11c. When a passage area of the gas passage is defined as S1, a passage area of the oil supply passage is S2, a passage area of the oil supply pipe is S3, a diameter of the diameter direction oil supply hole is d2, and a width of the axial direction oil supply groove in a rotational direction of a rotor is L, the passage area S2 of the oil supply passage is set to be in a range of S1
