摘要： A valve 100 comprising a magnetic circuit comprising a first member 101 and a pivotably mounted armature 102 the armature being movable between a position in which the valve seal 104 engages the valve seat 105 of valve port 103 to block the valve port 103, and a position away from the first member 101. A coil 106 surrounds the armature 102 which, when supplied with an electric current, creates a magnetic field in the armature 102 attracting the free end to the first member 101. Dampening pads 110 are provided on the armature 102. Each dampener pad 110 comprises a layer of viscoelastic material covered by a protective layer of polyetheretherketone (PEEK). During use, as there is wear between the armature 102 and the first member 101, and/or non magnetic section 107, the dampening pad 110 is compressed on impact by an increasing degree, thus the more worn the valve becomes, the more the dampening and thus the greater the protection against further wear.

摘要： A pump assembly comprises a cam and a piston. The cam rotates in a plane about an eccentric axis, and has a circumferential side wall. The piston engages the circumferential side wall of the cam, and runs along a piston axis which lies in the plane of the cam. The piston axis is parallel to but not coincident with a reference line perpendicular to and intersecting the eccentric axis.

摘要： A pump assembly comprises a base, a cam, a cylinder, a piston, and a shim clip. The cam rotates about a rotational axis with respect to the base. The cylinder attaches to the base, and has an inlet port and an outlet for fluid. The piston is reciprocally driven by rotation of the cam to draw fluid into the cylinder through the inlet port during a fill stroke, and to close the inlet port and pump fluid in the cylinder toward the offset during a pump stroke. The shim clip is removably insertable between the cylinder and the base to increase the distance between the inlet port and the rotational axis.
