摘要： A sensor (10, 110) for measuring a level (12, 112) of a fluid (14, 114) includes a member (16, 116) and a bobbin (20, 120) defining a cavity (22, 122) therethrough and configured for receiving the member (16, 116). The sensor (10, 110) also includes at least one inductive coil (18, 118) wound to the bobbin (20, 120), wherein the at least one inductive coil (18, 118) defines a plurality of symmetrical layers (30, 130) that each extend along an axial length (L) of the bobbin (20, 120). The sensor (10, 110) includes a float (38, 138) operably connected to the member (16, 116) and buoyant in a fluid (14, 114) having a level (12, 112) in a container (40, 140). The member (16, 116) axially translates within the cavity (22, 122) in response to a change in position of the float (38, 138) according to the level (12, 112) of the fluid (14, 114) so that an inductance of the at least one inductive coil (18, 118) varies in relation to a position (44, 144) of the member (16, 116) within the cavity (22, 122) and thereby in relation to the level (12, 112) of the fluid (14, 114).

摘要： A hydraulic control valve (10) is provided having a solenoid body (18), an energizable coil (22), and an armature (28) positioned adjacent the coil. A valve stem (48) extends from the armature. The coil is energizable to move the armature and the valve stem from a first position to a second position. The valve body, the armature and the valve stem are configured so that the armature and the valve stem are biased to the first position by pressurized fluid, allowing the armature to operate without a biasing spring.

摘要： A fluid condition and level sensor (12, 112) is provided that includes a solenoid body (20, 120), a coil (30, 130), and an armature (44, 144) surrounded by the coil. The solenoid body defines an armature chamber (42, 142) in which the armature is movable in response to energizing of the coil. The sensor is mounted to a reservoir (15, 115) such that a first portion (24, 124) of the solenoid body extends into a cavity (60, 160) defined by the reservoir, and so that movement of the armature is substantially transverse to a direction of fluid level change in the reservoir. The first portion of the solenoid body defines an opening (62, 162) permitting fluid communication between the cavity and the armature chamber, such that fluid enters and is displaced from the armature chamber through the opening as the armature moves, movement of the armature within the armature chamber thereby being affected by fluid level in the reservoir.
摘要翻译：提供了流体状态和液位传感器（12,112），其包括螺线管体（20,120），线圈（30,130）和由线圈包围的电枢（44,144）。螺线管本体限定衔铁室（42,142），其中电枢响应于线圈的通电而可移动。传感器安装到储存器（15,115），使得螺线管主体的第一部分（24,124）延伸到由储存器限定的空腔（60,160）中，并且使得电枢的运动基本上横向到储层中液位变化的方向。螺线管主体的第一部分限定允许空腔和电枢室之间的流体连通的开口（62,162），使得当电枢移动时，流体进入并且通过开口从衔铁室移位电枢室因此受到储存器中的液位的影响。
