摘要： A valve assembly for a pump includes a pump chamber and a pump head having complementary recesses formed therein which cooperate to define a valve compartment including a pocket and an opposed seat. A flexible valve element is disposed between the recesses and adapted to move between a closed position against the seat which prevents fluid flow and an open position away from the valve seat which permits fluid flow. The dimensions of the valve compartment are selected to limit the movement of the valve element in the open position, which increases the pump efficiency and prevents damage to the valve element and/or valve overlap.

摘要： A sealing arrangement for a pump includes a first member having a peripheral wedge-shaped pocket; a second member with a rim opposed to the pocket; and a diaphragm disposed between the two members. The diaphragm includes a central stem, a disk-shaped head attached to the stem, and an upstanding bead disposed around the periphery of the head. The bead includes a first angled surface and a second angled surface. The bead is received in the pocket so as to form two separate, spaced-apart sealing surfaces between the diaphragm and the first member. The sealing arrangement may also include a gasket made from a resilient material and having a flat web with a circular crosssection bead disposed in a gland between two members. The dimensions of the bead and the gland are selected such that the bead is diametrically compressed at least about 40% from its free state.
摘要翻译：泵的密封装置包括具有周边楔形袋的第一构件; 具有与口袋相对的边缘的第二构件; 以及设置在两个构件之间的隔膜。隔膜包括中心杆，附接到杆的盘形头部和围绕头部的周边设置的直立珠。珠包括第一倾斜表面和第二倾斜表面。胎圈被容纳在口袋中，以在膜片和第一构件之间形成两个分离的间隔开的密封表面。密封装置还可以包括由弹性材料制成的垫圈，并且具有扁平腹板，该平坦腹板具有设置在两个构件之间的压盖中的圆形横截面珠。选择胎圈和压盖的尺寸使得胎圈从其自由状态直径压缩至少约40％。

摘要： A valve assembly includes a housing having a valve bore, a valve seat, and at least one port communicating with the bore. A moveable plunger resides in the valve bore and selectively seals against the valve seat. A bobbin integral with the housing has a solenoid bore adjacent to and coaxial with the valve bore. A moveable armature resides in the solenoid bore and has an operating rod connected to the plunger. A pole piece resides in the solenoid bore adjacent the armature. A solenoid coil is wound about the bobbin. A flux conductor partially surrounding the bobbin, pole piece, and armature. An assembly method includes flowing air through the port, inserting the plunger or another sealing element into the bore while monitoring the fluid flow; and stopping the plunger or sealing element when the flow is at a preselected condition.

摘要： A electrical machine includes a housing assembly, first and second bearings mounted in the housing assembly, and a rotor assembly mounted in the bearings such that it has a predetermined amount of axial and radial play relative to the housing. A biasing element is disposed between one of the rotor assembly or the housing and one of the bearings. The biasing element urges the rotor assembly to a preloaded position which eliminates the axial and radial play. Each of the first inner and outer races and the second inner and outer races are secured to one of the rotor assembly or to the housing, such that the rotor assembly is retained in the preloaded position. The components of the electrical machine are chosen such that this preload is maintained over the operating temperature range of the machine.
