A fluid discharge valve includes a housing that defines a flow path configured to guide fluid, a partition that faces the flow path and is configured to move relative to the flow path, and a heater that is coupled and fixed to the housing and configured to supply heat to the flow path. The flow path includes a first flow path that is in fluid communication with an outside of the housing and extends along a first direction toward the partition, and a second flow path that extends from the first flow path along a second direction that crosses the first direction. The heater has a first side that faces the first flow path and a second side that face the second flow path.

A system for adjusting transmission oil temperature and a heat exchange assembly are provided. The heat exchange assembly includes a heat exchange core, a valve assembly, an adapter base, and a mounting plate fixed with the heat exchange core. The valve assembly is arranged in or partially located in a second passage of the heat exchange core. The valve assembly has a first valve port and a first notch. The heat exchange core further includes a through passage in communication with a fourth port. When a first valve port is opened, a third port is in communication with the fourth port through a first passage, the second passage, the first notch and the first valve port in turn. When the first valve port is closed, the third port is in communication with a fifth port through the first passage, the second passage and the first notch in turn.

A mixing valve that includes a housing having a first outlet, a second outlet, and a mixing chamber; a first flow control valve for controlling flow through the first outlet to the mixing chamber; and a second flow control valve for controlling flow through the second outlet to the mixing chamber; wherein the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

A fluid handling assembly comprising a cavity in which water may become trapped due to use of the assembly, and a membrane disposed in the cavity. The membrane divides the cavity into a first sub-cavity on a first side of the membrane that is configured to collect any water trapped in the cavity and a second sub-cavity on a second, opposite side of the membrane. The membrane is configured to change shape such that the first sub-cavity increases in volume and the second sub-cavity decreases in volume in response to being subjected to water freezing conditions. The increase in volume accommodates an increase in volume of any water that may be trapped in the first sub-cavity when it freezes to ice.

A fuel cell device is provided, including a media system for supplying fluid media to electrochemical units of the fuel cell device and/or for discharging fluid media from the electrochemical units of the fuel cell device, wherein the media system includes at least one valve to which, in a standard operating state of the fuel cell device, an electrical standard input power is suppliable in order to maintain the valve in a desired valve state. The fuel cell device is able to be reliably started with as little effort as possible, even under frost conditions. The fuel cell device is switchable into a heating operating state in which an electrical heating input power that is greater than the electrical standard input power is suppliable to the at least one valve.

An asparagus harvester includes a chassis movable over a bed of growing asparagus. Spears above a selected height are severed at the ground by a severing assembly. A conveyor receives from a pick-up apparatus and conveys away asparagus spears severed by the severing assembly. The severing assembly includes a severing blade carried by a plunger mounted in a pneumatic cylinder. Conduits couple the pneumatic cylinder to a source of air under pressure through a valve unit operable for actuating the pneumatic cylinder to repeatedly fire and withdraw the plunger for repeatedly moving the severing blade back-and-forth along a stroke path between a raised set position and a lowered severing position proximate to the ground. A heater mounted proximate to the valve unit is configured to sufficiently heat the valve unit to enable the valve unit to operate in the presence of an ambient temperature sufficiently low to impair its operation.

There is provided an apparatus comprising a torque motor comprising a spring, armature, flapper assembly (“SAFA”), a body, wherein the spring, armature, flapper assembly is mounted onto the body, and a cap enclosing the spring, armature, flapper assembly. One or more cooling passages are provided within the body and are configured to receive cooling air and direct the cooling air onto the spring, armature, flapper assembly of the torque motor.

A valve includes a valve housing having first and second regions, at least one valve chamber configured to be pressurized with air and including an actuating element for opening and closing a valve opening and an actuator for actuating the actuating element, both arranged in the first region. A printed circuit board extends into each valve chamber and to electrically operate the actuator, the printed circuit board(s) being connected to a common main printed circuit board arranged in the second region. Each valve chamber is surrounded by boundary surfaces closing the valve chamber in a substantially gas-tight manner. An open space open to at least two oppositely disposed sides of the valve housing extends between at least two of the valve chambers, and a connecting member of the printed circuit boards extends through connecting openings of the boundary surfaces of adjacent valve chambers and the open space. A sealing material located in the open space encloses the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides. A method of manufacturing such a valve includes manufacturing a conductor element including the printed circuit boards and the main printed circuit board; introducing the conductor element into the valve housing; and filling the open space at least in part with the sealing material from at least one side after the introducing step so that the sealing material seals the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides.

A fuel cell system includes a gas liquid separator and a valve device. The gas liquid separator separates water from a fuel off gas discharged from a fuel cell stack. The valve device is provided in a discharge channel for discharging water separated from the gas liquid separator. The valve device includes a fluid inlet for guiding fluid at least containing water in the gas liquid separator toward the valve main body. A heating device is provided at an inner hole of the fluid inlet.
