Abstract: It is an object of the invention to provide a cylinder cleaning device which is suitable for downsizing the printing press. The thick portions 10b, 10c of the pressure pad 10 are mounted on the grooved portions 42, 43 of the support bar 40. The engaged portions of the side plate 50 are disposed on the opposite sides of the thick portions 10b, 10c. The pressure pad 10 and the support bar 40 are nipped between and held by the engaged portions.

Abstract: A cleaning apparatus includes a pressure pad for a cleaning fabric. The pressure pad comprises a particular portion formed on a base portion. The base portion has a predetermined hardness. The particular portion has a predetermined hardness which is lower than the hardness of the base portion. The cleaning fabric is nipped between the particular portion and a subject to clean the subject with the cleaning fabric.

Abstract: There is disclosed a device for cleaning the cylinder of a printing press with a cleaning fabric. The device comprises a pad including a surface opposed to the cylinder. The cleaning fabric is directed between the surface of the pad and the cylinder, the surface of the pad being at least partially uneven. The device further comprises means for moving the surface of the pad toward the cylinder so that the cleaning fabric is pressed against the cylinder by the pad to clean the cylinder.

Abstract: A fuel supplying pump having a switching circuit provided in the pump closing. The switching circuit stops the pump when an engine stops rotating due, for instance, to a fuel pipe breakage. The circuit having a transistor with a base connected to an oil pressure responsive switch.

Abstract: An in-tank type fuel pump in which an impeller within the pump chamber is rotated by a motor disposed within a fuel chamber within a main body to pump fuel. A through hole in communication with a fuel chamber of the motor portion is provided in a side wall of the pump chamber on the motor side close to the upstream end of the annular channel defining the fuel chamber of the motor portion.

Abstract: An electric fuel pump is provided with an insulative holding member 20 for holding choke coils 16 and connecting portions 23 between the choke coils and lead wires (14) as well as between the choke coils and brushes 10, to be mounted in the interior of a pump frame 1. In this electric fuel pump, the insulative holding member 20 holds and fixes the choke coils 16 and the connecting portions around the same, thereby to protect the choke coils 16 and the nearby connecting portions against vibration and shocks applied to the fuel pump. The holding member 20 also insulates conductive parts so that the same are not in contact with a housing 1 of magnetic material or the like, thereby to improve insulativity.

Abstract: A suction port 22a of an end cover 22 and a suction port 21a of a pump casing 21 are disposed to have a certain angular distance from each other, and the end cover 22 is covered by fuel filtration element 23 with a gap against the bottom of the end cover 22, thereby resistance to fire flame ignited by collector of a pump motor becomes large and dangerous spreading of fire flame is prevented.

Abstract: An in-tank type fuel pump comprises a pump body having a cylindrical yoke with its one end closed by a cover-out member made of a synthetic resinous material, a motor held in the pump body and an impeller driven by the motor to discharge fuel sucked from an intake port to a discharge port, wherein an elongated portion extending along the inner wall of the cylindrical yoke is formed integrally with the cover-out member and each of first lead wires is extended from the interior of the pump body to the exterior of the same through each through hole formed in the elongated portion, each one end of the first lead wires in the pump body being connected to each of second lead wires connected to brushes.

Abstract: A rotary positive displacement pump of the pin roller type comprising a pump housing made of aluminum having a pump chamber with the inner periphery being cylindrical, which is fixed between a pump base and a pump case, a rotor eccentrically located within the pump chamber and driven by a motor, a plurality of rollers made of synthetic resin which is inserted in clearance grooves formed on the outer periphery of the rotor, wherein a centrifugal force generated when the rotor rotates moves the rollers toward the inner wall of the pump housing thereby to form a pump operation space.
