摘要： A cylinder head for a compressor includes a closure device that can be adjusted between an unactuated position (off-load) in which the compressor delivers air and an actuated position (off-load) in which the compressor is running in an idle mode, a pneumatic control device having a control cylinder and a control piston that can be moved in the control cylinder, a spring device that prestresses the closure device into the unactuated position (on-load), and a driver configured to couple the control piston to the closure device. The closure device closes a compressed air passage in the unactuated position (on-load) and clears the compressed air passage in the actuated position (off-load), and the driver is permanently connected to the closure device and can be driven by the control piston.

摘要： An installation for the production of pressure has three operating states corresponding to a delivery operation, an idle operation, and a partial delivery operation. The installation contains at least two compression chambers in at least one compressor, each chamber being assigned at least one switchable inlet valve. In the delivery operation, the switchable inlet valves act as check-valves that allow pressure medium to flow into their respective compression chambers. Each compression chamber also contains at least one outlet check valve through which compressed pressure medium flows out to a pressure consuming system in the delivery operation. Each switchable inlet valve also has an idling position that allows pressure medium to flow into the applicable compression chamber and back out again without being substantially compressed. In the idle operation of the installation, each switchable inlet valve switches to its idling position. In the partial delivery operation, one of the switchable inlet valves independently switches to its idling position, while the other inlet valve remains in its rest position, thus resulting in only partial delivery of the pressure medium to the pressure consuming system.

摘要： A stroke piston for a stroke piston compressor for generating compressed air for a vehicle, such as a commercial vehicle, includes a piston body with a piston floor, a piston skirt with piston skirt walls and pin hubs for receiving a piston pin, and at least two piston rings, which can be inserted into circumferential ring grooves of the piston body. Ridges of the piston body are provided between each two ring grooves and between the piston floor and the first ring groove arranged closest to the piston floor and the ring groove arranged closest to the piston skirt facing away from the other ring groove or grooves. At least one of the ridges is recessed at least over a partial section of its ridge height, which is measured parallel to the axis of the piston body, with at least one recess relative to the diameter of the piston body.

摘要： A safety valve arrangement for an installation operating with a pressure medium has a pressure medium input and a pressure medium output connected by a valve. The valve comprises a valve seat and a valve closing element. The valve closing element is moveable between an open position and a closed position and has an active surface that is subjected to the pressure medium in the opening direction of the valve. The valve closing element also has an auxiliary surface that is subjected to the pressure medium in the opening direction of the valve only when the valve closing element is lifted from the valve seat. A spring arrangement holds the valve closing element closed and the valve closing element moves from a closed position to an open position when the pressure medium acting upon the valve closing element is greater than the opposing force of the spring arrangement acting upon the valve closing element. The safety valve also has an auxiliary valve which also connects the pressure medium input to said pressure medium output. The auxiliary valve is moveable from an open position to a closed position. The spring arrangement also holds the valve closing element of the auxiliary valve closed. The valve closing element of the auxiliary valve is opened when the force of the pressure medium acting upon the valve closing element is greater than the opposing force of the spring arrangement acting upon the auxiliary valve closing element. The safety valve arrangement may also have a choke located between the valve and the pressure medium output which throttles the flow of the pressure medium.

摘要： A compressed air installation having a normal operating mode and an idling mode includes a feed valve, a feed line which is connected to and receives air through the feed valve, at least one compressor having at least one compression chamber, and at least one inlet valve which is connected to the feed line and supplies air to the compression chamber. The feed valve and the inlet valve are switchable between open positions and one-way positions wherein air can pass through the valve in one direction only. In normal operating mode, the feed valve is in its open position and the inlet valve is in its one-way position, thereby allowing air to enter and exit the installation through the feed valve and the feed line, and to pass from the feed line through the inlet valve into the compression chamber. When the compressed air supply installation is in idling mode, the inlet valve is in its open position and the feed valve is in its one-way position, thereby allowing air to enter the installation through the feed valve and into the feed line, and to enter and exit the compression chamber through the feed line. In a first alternative embodiment, the feed valve is switchable between open and closed positions, while the inlet valve is switchable between a one-way position in normal operating mode and an open position in idling mode.
