摘要： In a preferred form, this disclosure relates to a flow switch assembly comprising a housing means having a pair of hollow metal housing members which are insulated from each other and which define a flow passage therethrough. The assembly also includes a vane member which is pivotally supported for movement between first and second positions and a spring member which biases the vane member to its first position and normally has its opposite ends engaged with the metal members to provide a conductive path therebetween. The housing means has a recess which extends radially from the flow passage at a location between the first and second positions of the vane member. The vane member is moved from its first toward its second position in response to a fluid flow in excess of a first predetermined magnitude flowing therethrough to break the conductive path and, when the flow decreases to below a second predetermined magnitude less than the first, the vane member moves toward its first position. The recess provides an instantaneous increase in the flow passage area available for fluid flow when the vane member moves toward its first position and is aligned therewith to enable the spring member to rapidly shift the vane member to is first position.

摘要翻译： 在一个优选形式中，本公开涉及一种流量开关组件，其包括具有一对中空金属壳体构件的壳体装置，它们彼此绝缘并且限定通过其中的流动通道。 该组件还包括一个叶片构件，该叶片构件枢转地支撑在第一和第二位置之间运动，弹簧构件将叶片构件偏置到其第一位置，并且通常具有与金属构件接合的相对端，以在它们之间提供导电路径。 壳体装置具有在叶片构件的第一和第二位置之间的位置处从流动通道径向延伸的凹部。 响应于超过流过其中的第一预定大小的流体流动，叶片构件从其第一位置移动到其第二位置以破坏导电路径，并且当流量减小到小于第一预定量级的第二预定量值时， 叶片构件朝向其第一位置移动。 当叶片构件向其第一位置移动并与其对准时，凹部提供可用于流体流动的流动通道面积的瞬时增加，使得弹簧构件能够将叶片构件快速地移动到第一位置。

摘要： A radial piston hydraulic motor in which a valve, rotatably driven by the motor output, through a drive pin, provides timed fluid flow to and from the motor cylinders relative to rotation of the motor output. If the valve should seize in the cylinder housing, the pin will shear, opening a passage therein, to provide a fluid flow connection between the high pressure side of the motor and the motor case to prevent a hydraulic lock from forming in the cylinders.
