摘要： The invention relates to valve control apparatus for controlling the opening and closing of an inlet and/or exhaust valve of an engine or compressor. With reference to Figure 2, the apparatus comprises a piston and cylinder arrangement (40) having at least one chamber (44) and a piston (42) connected to the inlet or exhaust valve (21, 22) such that motion of the piston (42) within the cylinder (41) causes motion of the inlet or exhaust valve (21, 22). The apparatus also comprises means (11) for connection to a source of pressurised fluid (12) and means (13) for connection to an exhaust for pressurised fluid (14). The apparatus further comprises an electrical or electronic control device (23) and a valve means (100) controlled by the control device (23). The valve means (100) has three operating conditions, a first in which the valve means (100) connects a first chamber (44) of the piston and cylinder arrangement (40) to the source of pressurised fluid (12), a second in which the valve means (100) connects the first chamber (44) to the exhaust for pressurised fluid (14) and a third in which the valve means (100) isolates the first chamber (44) to prevent flow of fluid into or out of the chamber. The control device (23) controls motion of the piston (42) by selectively controlling the valve means (100) to operate in one of the three operating conditions and by controlling the length of time that the valve means (10O) operates in the chosen operating condition.

摘要： A vehicle gear change mechanism is provided to enable a gear change to be effected with a conventional gearbox without manually moving the gears. The gear changes are effected by an actuator (20) which is hydraulically powered and is controlled by control means including a control unit (17). The actuator (20) is operated such that the force applied to effect a gear change is varied to be reducible during gear engagement. In one arrangement this is achieved by controlling the supply of hydraulic fluid through valve means (102, 104, 130) and a hydraulic accumulator (131). There is also provided means for controlling operation of a clutch to the gearbox whereby smooth gear changes are effected.

摘要： The present invention provides a method of testing an engine or compressor wherein an inlet and/or exhaust valve (19) is actuated by a hydraulic piston and cylinder arrangement (11) and the flow of hydraulic fluid to the piston and cylinder arrangement (11) is controlled, variation of the motion of the valve (19) being achieved by adjustment of the control means (14, 10) for controlling the hydraulic fluid. Preferably the control means is programmed such that the motion of the valve (11) corresponds to the motion that would result from the use of a particular camshaft in the engine or compressor to control valve motion. The invention also provides apparatus for use in the method.

摘要： The present invention relates to actuator (11) comprising a piston (16) with a cylinder (17). The piston (16) divides the cylinder (17) with at least two chambers. An orifice (53) is provided in an end surface of the cylinder (17). The said end surface and the nearest piston surface are shaped so that as the piston (16) approaches the said end surface the flow of fluid from between the said end surface and the said piston surface to the orifice is restricted. Preferably the end surface and the piston (16) define between them two subchambers (54, 57) and an interconnecting passage (58) for the last portion of motion of the piston (16) towards the end surface. The passage (58) decreases in size as the piston (16) approaches the end surface and increasingly restricts flow of fluid between the two subchambers (57, 54).

摘要： The present invention relates to valve control apparatus for use in an engine or compressor to open and close an inlet or exhaust port thereof which comprises valve means (19), an irreversible hydraulic actuator (11) and control means (10, 40). The actuator (11) is connected to the valve means (19) such that the valve means (19) can only operate when driven by the actuator (11). The actuator (11) is irreversible since the piston (16) with the actuator (11) cannot move unless fluid is introduced into one of the chambers of the actuator and removed from the other.
摘要翻译：本发明涉及一种用于发动机或压缩机的阀门控制装置，其用于打开和关闭其入口或排气口，其包括阀装置（19），不可逆液压致动器（11）和控制装置（10,40）。致动器（11）连接到阀装置（19），使得阀装置（19）只能在由致动器（11）驱动时操作。致动器（11）是不可逆的，因为具有致动器（11）的活塞（16）不能移动，除非流体被引入致动器的一个腔室并从另一个腔室中移除。
