摘要: A fuel pump for a vehicular diesel fuel pump member having a control valve assembly which includes a housing having a control valve chamber, and an actuatable control valve disposed in the control valve chamber. The control valve includes a piston valve body axially movable over a motion displacement interval between first and second positions. The motion displacement interval is defined by first and second sub-intervals bounded by the first and second positions, respectively. The control valve assembly further includes means for actuating the control valve. A valve stop is disposed in the housing adjacent the control valve chamber, and a piston valve body seat contacts the valve stop whenever the piston valve body is in the second position. The piston valve body seat contacts a pump body seating surface whenever the piston valve body is in the first position. A first control valve spring resiliently biases the piston valve body toward the unactuated position whenever the piston valve body is in the first sub-interval. A second control valve spring resiliently biases the piston valve body into damped engagement with the valve stop whenever the piston valve body is in the second sub-interval.

摘要: An adjustable rotor and/or a radial piston machine which may utilize an adjustable rotor. The rotor has a primary eccentric rotatable around an axis and a secondary eccentric adjustable in position relative to the primary eccentric. The radial piston machine includes a plurality of piston cartridges arranged radially around the axis and both high pressure and low pressure fluid distribution systems. Multiple units may be axially coupled. A single unit may handle a variety of fluids in various combinations.

摘要: A low contamination double bellows pump suitable for providing relatively constant pressure and delivery. The illustrated pump includes two pumping chambers with bellows arranged in opposed relationship on opposite sides of a central section. The central section acts as a valve body for inlet and outlet valves. The bellows are provided with interior bellows tubes which connect to the free ends of the bellows and slide upon stationary support pistons mounted within each tube. Bellows tube head pieces slide upon piston rods which support the pistons. Pneumatic pressure is controllably supplied to opposing sides of the pistons within the bellows tubes to power the bellows and effect pumping.

摘要: A double acting pump is provided for pumping air in one cylinder and liquid mix into another. The cylinders and valve housings, together with the inlet and outlet fittings, are readily separable for cleaning. The entire pump unit may be disassembled for cleaning by the removal of four knobs or nuts.
