摘要： The present invention, in one aspect, is a pressure responsive valve for a marine engine that facilitates balanced operation of the engine. In an exemplary embodiment, the valve includes a first chamber and a second chamber. Coolant is in flow communication with the valve first chamber, and the engine cylinder head water jackets are in flow communication with the valve second chamber. A flow channel is between the valve first and second chambers, and a plunger is biased to close the flow channel to normally prevent flow from the first chamber to the second chamber. A diaphragm is coupled to the plunger and is responsive to pressure in the first chamber. During operation of the engine at low revolutions per minute (rpm), the pressure of the coolant in the valve first chamber is not sufficient to cause the diaphragm to move the plunger to the open position. As the engine speed increases, the pressure of the coolant also increases. Once the engine speed reaches a sufficiently high rpm so that the coolant pressure exceeds a pre-set pressure, then the coolant pressure in the first chamber causes the plunger to move to the open position. When the plunger is in the open position, coolant flows from the first chamber to the second chamber. As a result, coolant flows through the valve to the cylinder head cooling jackets.
摘要翻译：本发明在一个方面是用于船用发动机的压力响应阀，其有利于发动机的平衡运行。在示例性实施例中，阀包括第一室和第二室。冷却剂与阀第一室流体连通，发动机气缸盖水套与阀第二室流通。流动通道在阀门第一和第二室之间，并且柱塞被偏置以关闭流动通道，以正常地防止从第一室流向第二室。隔膜联接到柱塞并且响应于第一室中的压力。在以每分钟低转速（rpm）发动机运转时，阀门第一室中的冷却剂的压力不足以使隔膜将柱塞移动到打开位置。随着发动机转速的增加，冷却剂的压力也增加。一旦发动机速度达到足够高的转速，使得冷却剂压力超过预设压力，则第一室中的冷却剂压力使柱塞移动到打开位置。当柱塞处于打开位置时，冷却剂从第一室流向第二室。结果，冷却剂流过阀门到气缸盖冷却夹套。

摘要： In a case where no malfunction occurs in a water temperature control valve the temperature of the pump water is controlled to accurately follow a target water temperature. In contrast, in a case where the rotational opening degree of the water temperature control valve is accidentally fixed, the pump water temperature can no longer follow the target water temperature. In this instance, a control water temperature error between the target water temperature and the pump water temperature is calculated. When the control water temperature error is greater than a certain error range, a counter is incremented, and a malfunction judgment flag is set when the value of the counter exceeds a certain judgment threshold value at another time. Thereby, the temperature of the cooling water for the engine is feedback controlled while malfunction of the water temperature control valve can be accurately detected.
摘要翻译：在水温控制阀不发生故障的情况下，泵水的温度被控制以准确地跟随目标水温。相反，在水温控制阀的旋转开度意外地固定的情况下，泵水温度不能再跟随目标水温。在这种情况下，计算目标水温与泵水温度之间的控制水温度误差。当控制水温度误差大于某个误差范围时，计数器增加，当计数器的值在另一时间超过某个判定阈值时，设定故障判定标志。由此，可以在对水温控制阀的故障进行准确检测的同时反馈控制发动机的冷却水的温度。

摘要： An engine cooling system controls a cooling degree of an engine 1 according to an operating condition thereof by circulating cooling water through the engine. This system is provided with a flow rate regulating valve 8 for regulating a circulation flow rate of the cooling water. An electronic control unit (ECU) 30 controls the valve 8 to open at a predetermined opening when determining the engine 1 as being stopped. In this opening control, the ECU 30 controls to bring a valve element into contact with a valve body once and then move the valve element to determine the predetermined opening with reference to a full-closed position of the valve element.

摘要： An apparatus for controlling a temperature of an engine by controlling the flow of a liquid engine coolant to a radiator is disclosed. The apparatus includes a thermostat having a thermally responsive valve for substantially blocking or opening the flow of coolant to the radiator to maintain the engine at or about a preferred engine operating temperature. Also included is a thermally activated actuator for opening the valve in response to an engine condition such as load or a need for power. The actuator is activated at a temperature different than the thermostat. A source of electro thermal energy is provided to motivate the actuator so the valve may be opened on demand. In one aspect the invention provides a method of controlling the temperature of the engine by opening the valve in response to engine monitoring.

摘要： A cooling circuit for an internal combustion engine has a main heat exchanger for cooling cooling medium circulating in the cooling circuit. A secondary heat exchanger provides heating of heating air to be supplied to a vehicle interior. A thermostatic valve has a simple design which makes it possible to heat the vehicle interior even in the case of a maximum cooling capacity for the internal combustion engine. An inlet of the thermostatic valve is connected to an outlet of the internal combustion engine and a first outlet of the thermostatic valve is connected to an inlet of the main heat exchanger. An outlet of the main heat exchanger is connected to an inlet of the internal combustion engine and a second outlet of the thermostatic valve is connected to the inlet of the internal combustion engine via a short-circuit line. An inlet of the secondary heat exchanger is connected to the second outlet of the thermostatic valve and an outlet of the secondary heat exchanger is connected to the inlet of the internal combustion engine. The thermostatic valve is designed in such a way that, in a first end position (cooling mode), it fully opens the first outlet and throttles the second outlet, in an intermediate position (mixed mode) it opens the first and second outlets to a greater or lesser extent and, in a second end position (warm-up mode), it blocks the first outlet and fully opens the second outlet.

摘要： A thermostatic valve arranged in the coolant circuit of an internal-combustion engine, has a main valve which is acted upon by cold coolant flow on the one side, and by hot coolant flow on the other side. The valve is actuated as a function of the coolant temperature by way of an expansion material element equipped with an electric heating device. To minimize the coldside influence onto the expansion material element, a capsule which stores the expansion material, has an end which limits the expansion material lower at the level of the closed main valve or on the mixing chamber side. At this end, a ring-shaped or sleeve-shaped heating element is arranged coaxially adjacent the control pin, or, individual heating elements are distributed along the circumference of the control pin in an adjacent manner.
