Abstract: Oil flows into the control valve body past the float controlled inlet valve to maintain a constant level in the body. The thin metering disc is rotatable to multiple positions in which a metering orifice underlies the float chamber outlet to accurately meter the flow. The disc is biased against the outlet by a spring which gives a constant spring force on the disc. The disc is turned by means of the manual knob operating a shaft at the lower end of which is a detent star wheel keyed to the shaft and engaged by springs which engage the valleys in the wheel to properly position the metering disc with a selected orifice in registry with the outlet. The detent arrangement does not impose any vertical loading on the shaft and cannot affect the spring force acting on the disc. The opposed springs acting on the star wheel balance each other so far as any load on the shaft is concerned. When the knob is turned to ''''off,'''' the spring arm acts on the link to lift the float and force the inlet valve closed. If the oil level rises too high (due to leakage at the inlet valve), the inverted L-shaped safety float flips clockwise to wedge in the valve closed position until manually reset.

Abstract translation: 油通过浮子控制入口阀流入控制阀体，以保持体内恒定的水平。 薄计量盘可旋转到多个位置，在该位置中，计量孔位于浮子室出口下方，以精确地计量流量。 光盘通过弹簧偏置在出口上，弹簧在盘上产生恒定的弹簧力。 通过手动旋钮操作盘旋转盘，该手柄在其下端处是与该轴相连的止动星轮，并与弹簧接合，该弹簧与车轮中的谷接合，以使计量盘以选定的孔适当地定位 与插座注册。 制动装置不会对轴施加任何垂直载荷，并且不会影响作用在盘上的弹簧力。 作用在星形轮上的相对弹簧相对于轴上的任何载荷都相互平衡。 当旋钮转到“关闭”时，弹簧臂作用在连杆上以提升浮子并迫使进气阀关闭。 如果油位上升太高（由于进气阀泄漏），倒L型安全浮子顺时针翻转，楔入阀门关闭位置，直到手动复位。

Abstract: The flanged end of the plunger guide which fits into the enlarged end of the wax element cup has a chamfer which seats against the internal shoulder when the clamping is completed. Inside the chamfer is a flat leading to a downwardly radiused clamp portion which develops maximum compression of the elastomeric diaphragm. The radius and the chamfer both force the elastomer to flow outwardly to effect a superior seal. The diaphragm face remote from the wax charge has a generally annular recess (which appears to dis-appear after clamping) to reduce the friction between the diaphragm and the guide to thereby facilitate stretching the diaphragm over a maximum area.
